The four Russians citizens who gang-raped a fellow student at an exclusive college were locked up on Tuesday, Mirror reported.
Oleg Ivanov, Gregory Andreev Melnikov, Norayr Davtyan and Armen Simonyan filmed the sickening two-and-a half-hour attack after bragging on camera what they were going to do to their defenceless victim whose drink had been spiked, Tert.am reported.
Two of them - Davtyan and Simonyan - were ethnic Armenians.
Judge Peter Murphy told a court: "The iPhone footage shows what can only be described as a callous disregard for the victim as a human being and indeed as anything other than an object of their own pleasure.
"No one who has seen that footage can leave this trial without feeling complete disgust.
"Although there was no pre-existing plan, once the sequence of events started, they were encouraging each other to do more and more.
"They were clearly seen on the iPhone celebrating their triumph almost in the manner of -professional footballers ¬celebrating the scoring of a goal. They also boasted that they would show the footage to anyone in Moscow."
Ringleader Davtyan, 22, a water polo international, was jailed for 10 years. ¬Melnikov, 23, got nine years while Ivanov, 23, and 19-year-old Simonyan were each caged for eight years at Woolwich crown court. The four had gone to a disco at the college in January where they were studying to get into British universities.
Davtyan held an impromptu party in his room in the halls of residence at Deptford not too far from the college. The victim went there at around 7pm and had a shot of whisky before leaving. She became dizzy and felt her drink had been spiked.
CCTV captured her stumbling though the main entrance and filmed her in a smoking area talking to Ivanov and Melnikov.
She was later seen walking away with Melnikov to the party in Davtyan's room. Once there she vomited and lay on the floor.
She was eventually left alone with the four men and footage from Davtyan's phone shows her being raped by the baying mob.
The gang had all denied rape but were convicted. They tried to claim the victim had consented.
