Muir was released by Saints last summer and moved to third division Elgin City. A club source has revealed that Saints were aware the police had stopped Muir, but hadn't realised this was why. They go on to claim that this was not the reason the young midfielder was released by the club.
The SFA have announced that they will now investigate the manner. Muir is not the first Saints player to be involved in a drugs scandal, as in the mid 1990s Barry Lavety was sent to a rehab clinic after admitting taking ecstacy.
