Ross had been drinking
beer from a
can. Without his knowledge, five or six tablets of
temazepam and some of
LSD was put into his can. He ended up consuming the drugs alongside the beer. Thirty minutes after having consumed the drink, he started screaming and indiscriminately attacking other people with a knife. Several people were severely injured. Ross
resisted arrest by the police and stopped screaming only after they had
handcuffed him. He continued to struggle until he was taken to a hospital and administered a
sedative drug. The
High Court at
Glasgow tried Ross for various charges including nine counts of
assault and seven counts of
attempted murder. The jury found Ross guilty on several of the charges but found that while he committed the offences, he had been
influenced by the drugs that were
administered to him without his knowledge. He has appealed against his conviction on the ground that the trial judge misdirected the jury that they could not acquit him of the charges of which he was convicted. Ross appealed the decision to the
Court of Criminal Appeal. He argued that the trial judge had misdirected the jury by telling them that they could not acquit Ross of the offences, in spite of his involuntary intoxication. ==Appellate decision==
