LONDON -- The joyful spirit from the 2012 London Games has gone from the Olympic Stadium, replaced instead by hatred and ugly skirmishes.West Hams new home, converted into a soccer stadium with the seats newly painted in the teams claret and blue colors, has been marred by violence this season as small mobs create a toxic atmosphere during matches.Further disorder erupted in the closing stages of Wednesdays game against Chelsea, with bottles, coins and seats hurled between rival fans and seven people arrested. Such unrest -- and far worse -- was a regular occurrence in the last century, but English authorities thought they had contained the problem.Football has become a better, more welcoming environment for a wider fan base, sports minister Tracey Crouch said Thursday. No one wants to see a return to the dark days of the late `70s and `80s. It is completely right that strong action is taken and that anyone involved in last nights trouble is banned for life.Later Thursday, West Ham and London Stadium said in a statement that they are finalizing the identification of 200 individuals who will receive stadium bans having been involved in incidents of disorder ranging from the use of abusive and offensive language to missile throwing.The statement added that rapid progress has been made thanks to extensive CCTV footage being shared between the two London clubs, the Metropolitan police and London Stadium partners.The cause of the disturbances, which Crouch called desperately sad, is perplexing authorities. Why should a club, which was renowned in the past for hooliganism, see a revival of a violent element of its fan base just by moving a few miles across east London from Upton Park?Security numbers were increased inside the stands and riot police stationed around the streets of Stratford for the visit of Chelsea. But there are problems segregating fans in a stadium that was not initially designed for soccer and had to be partially rebuilt after the Olympics to make it suitable for West Ham, which has a 99-year lease.Although Wednesdays game was a London derby, it was in Englands second-tier League Cup competition when weaker lineups are typically used by teams. And beating Chelsea 2-1 to advance to the quarterfinals produced a rare bright moment this season.But a visiting Chelsea fan said he was hit by an object soon after Cheikhou Kouyate headed West Ham in front in the 11th minute.As soon as they scored there was abuse being hurled over and we were watching the game and all of a sudden I felt a massive thump on the side of my head, thinking it was a bottle or a stone, Steve Cutting said. I put my hand up to my head and realized Id been cut. I looked down and there were some coins, 50p (pence) and pound coins.The English Football Association has opened an investigation into the latest disturbances. The English Football League, the organizers of the League Cup, is working with the clubs and authorities to identify the perpetrators of the violence.West Ham was known for having an organized group of hostile supporters called the Inter City Firm, active mostly in the 1970s and `80s and at away games. The movie Green Street, released in 2005, was based on the group. Behavior among West Ham fans significantly improved in recent years, although there have been isolated incidents, including at the clubs last game at Upton Park in May when the Manchester United team bus was attacked.West Hams inability to shake off its harmful image of a small section of its fan base may hamper attempts to secure naming rights for its new stadium.Olympic Stadiums dont generally make great naming rights sponsors, Tim Crow, chief executive of sports marketing agency Synergy, said by telephone. Very few have attracted a naming rights sponsor and as a result London was up against it anyway.What last night and previous incidents have done is make it extremely unlikely we will see anything happening in the near future and maybe longer.---Rob Harris is at www.twitter.com/RobHarris and www.facebook.com/RobHarrisReportsAuthentic Custom Steelers Jersey .

SACRAMENTO, Calif. -- Just a few years ago, NBA Commissioner Adam Silver had a hard time envisioning seeing this day come.He stood outside a Sacramentos new state-of-the-art downtown arena and welcomed Kings fans to the home opener for a franchise many believed was on its way out of town just over three years ago.I think its a borderline miracle from where we were in 2013 to be here in 2016, a year earlier than they originally pledged to have an arena done, Silver said Thursday before the Kings hosted San Antonio in the first regular-season game at the Golden 1 Center. To be done, to be here on opening night with the building completely finished with strong local ownership, its everything a league could hope for.The idea seemed far-fetched back in the spring of 2013 when the Maloof family was poised to sell the team to a group of Seattle investors seeking to move the franchise to the Pacific Northwest.But tech mogul Vivek Ranadive stepped up to buy the team for $534 million and keep it in Californias capital city with a new arena that Silver calls the new standard in the NBA.The 17,500-seat arena is the first professional sports venue powered completely by solar energy, will save about a million gallons of water a year compared to a typical venue of its size, was built with recycled material from the mall that stood at the site before construction began and will get 90 percent of its food and beverages from within 150 miles.It became the first indoor venue to receive LEED Platinum certification -- the highest level of recognition for environmentally conscious buildings.There are other features like the NBAs first 4K ultra HD videoboard -- providing a picture four times clearer than HDD -- and an in-arena app that allows fans to control the temperature at their own seat.dddddddddddd.The arena is part of a $1 billion development project that includes 1.5 million square feet of mixed-use property that will have a hotel, restaurants, retail shops, offices and condos. About $500 million in outside investment is also expected in the area.These are true modern day town halls, Silver said. You can see from the smiles on the fans faces as they were walking in, there was sort of a collective `Wow!Among the most unique features are the airplane hangar doors that can be opened to turn the venue into an indoor-outdoor arena. The team tested it out for parts of three preseason games and saw no measurable differences in temperature, humidity or wind on the court and would like to be able to open the doors during games eventually.The league wants to do additional tests and consult with other teams before coming up with a protocol for when the doors can be open.Because its so new, we want to make sure we get it right, he said. It will probably be a few more weeks. Our hope is it will be done well before this season will be over.Silver also said there is an opportunity for an All-Star game to come here, saying the team has presented a plan to have visitors stay on cruise ships in the Sacramento River delta to make up for a lack of hotel rooms.Sacramento has beaten the odds so many times before, Silver said. Initially at first blush, it was `Wed love to come here but you dont have enough hotel rooms. But there is a true can-do attitude here in Sacramento. ' ' '
