The International Olympic Committee has confirmed that 23 competitors from the 2012 London Olympics have failed doping retests. The IOC said 265 London samples had been retested with improved techniques, and the 23 failures come from competitors from six countries, competing across five sports.The athletes have not been named but Sky Sports News HQ understands that no British athletes are involved. It is understood there has been no contact between the IOC and the BOA over the matter, and that no British athlete has returned a positive sample.The London athletes are in addition to the 31 caught in retests of samples from the 2008 Beijing Olympics. The Russian Olympic Committee has confirmed that 14 of those athletes were Russians.The IOC still has to retest the athletes B samples. Formal positive cases are not declared until the B samples confirm the original findings.The IOC said the retests targeted athletes who were hoping to compete at the Olympics in Rio de Janeiro in August.IOC president Thomas Bach said: These reanalyses show, once again, our determination in the fight against doping.We want to keep the dopers away from the Olympic Games in Rio de Janeiro. This is why we are acting swiftly now.I have already appointed a disciplinary commission, which has the full power to take all the decisions on behalf of the IOC. It was also revealed that one more sample from Beijing had shown abnormal parameters and would also be followed up on.The samples were re-examined after intelligence-gathering that began last August, the IOC said in a statement.It has been working with the World Anti-Doping Agency (WADA) during that period.UK Anti-Doping (UKAD), meanwhile, welcomed the reanalysis of samples from both the Beijing and London Olympics.The ability to retest samples, as a result of new intelligence or the development of new testing techniques, is a vital tool in the fight against doping in sport, said UKADs director of operations Pat Myhill.Retrospective analysis allows us to pursue those who cheat clean athletes, long after the competition has ended.It sends a clear message to those who dope - if you chose to make that choice, and think that youve got away with it, think again. We can, and will, catch you.

Prosecutors countered that they can show Hernandez was with Odin Lloyd when he was shot and that Lloyds killing was part of a pattern of Hernandez committing acts of violence following nightclub disputes. Also Monday, the former tight end pleaded not guilty to charges that he attacked a handcuffed inmate and threatened to kill a guard and his family while at a county jail in Dartmouth. Hernandez faces murder charges in Lloyds June 17, 2013, slaying, as well as a separate case in which he is accused of gunning down two men in Boston in July 2012. He has pleaded not guilty in each case and is being held without bail. Judge E. Susan Garsh will rule at a later date on the motions to dismiss the Lloyd murder charge and to suppress certain evidence gathered by the state, including cellphone records and surveillance video from dozens of cameras at Hernandezs North Attleborough home. The judge on Monday also floated a possible trial date of Oct. 6, and she set a July deadline for the New England Patriots to respond to the defences requests for access to the football teams personnel records. Hernandez defence attorney James Sultan called the prosecutions evidence "woefully lacking" and maintained that the state has yet to suggest a specific motive for Lloyds killing. "Theres certainly a lot of what I would call smoke. No doubt about it," Sultan said. "But you cant throw a bunch of stuff at the wall and say, Well, thhats good enough.ddddddddddddThats not probable cause that he committed the crime." Prosecutor William McCauley countered that the state has "powerful" evidence against Hernandez. In what amounted to a preview of the states arguments, he said toll booth, surveillance, GPS and cellphone records clearly place Hernandez in the car with Lloyd at the time of his murder. McCauley said the states evidence also shows Hernandez had the "presence, knowledge and intent" to see the murder to its completion. Prosecutors also suggested incidents in Boston, Providence and Miami show a "common pattern" of violence by Hernandez following disputes at nightclubs. But Hernandezs lawyers pushed back against that notion, saying it was part of a persistent attempt to trash Hernandezs character. They criticized prosecutors for their focus on his "affinity for guns," his drug use and past run-ins with law enforcement. Lloyd had been at a Boston nightclub with Hernandez and others days before his bullet-ridden body was found about a half mile from Hernandezs North Attleborough home. Prosecutors in Boston have said a spilled drink in a nightclub led Hernandez to kill two people in a drive-by shooting. Another Hernandez associate, Alexander Bradley, has filed a civil lawsuit alleging Hernandez shot him in the face on Feb. 13, 2013, after they argued following a visit to a Miami strip club. Dressed in a blue blazer and khaki dress pants, Hernandez sat passively through Mondays nearly three-hour court hearing, one of the longest since his arrest last year. His mother and other supporters sat in the audience, as did Lloyds mother and others. ' ' '
