Hugh Derby has been jailed for 12 years for a number of offences. It was found that he targeted three of his victims while they were sleeping under the influence of drink.
The accused also took part in the gang rape of a 15-year-old girl after she was intoxicated with drink and drugs.
Mr Debry denied a serious of charges during an earlier trial but was convicted of four offences of sexual assault. He had then gone on to claim that some of his victims had consented and that on the other occasions the offences did not take place.
However, he was found guilty for a number of offences and was jailed at The High Court in Edinburgh and was also placed on the sex offenders register indefinitely.
