A knife found at OJ Simpson's former LA home was not the weapon used in the 1994 murders he was cleared of committing.
Police in Los Angeles say they carried out a range of forensic tests on the blade before ruling it out.
In 1995 Simpson was sensationally acquitted of stabbing his ex-wife Nicole Brown and her friend Ronald Goldman.
The retired American football player, broadcaster and actor has been back in the headlines recently with the FX drama The People v. OJ Simpson recently airing in the States.
