Details of his time in prison in this 2001 Times article. Mentions bottle attack.
In a variety of prisons, Bamber seems to have been treated in a remarkably indulgent way - despite being troublesome. At Long Lartin, Worcestershire, he was given the key to his cell and excused prison work so he could study for GCSE sociology and media studies. He had a daily badminton session after breakfast at 8am and earned extra money by having an agent outside who sold pictures of supermodels that he had drawn in art class. He boasted that he had three relationships with women inside prison (one with a trainee policewoman) and regularly received a mailbag of 50 letters a week from admiring females.
Bamber's funds were also boosted when he received "thousands of pounds" in compensation for whiplash injuries he received when a lorry crashed into a van moving him between prisons. The prison also paid him compensation when a Gameboy was stolen from his cell.
He once attacked another prisoner with a broken bottle, however, and was put in solitary confinement when he angered other inmates by revealing too much about their comfortable lifestyles to journalists. Even before Bamber created his website earlier this year, he seemed to have unusual access to the media for a convicted murderer. From Whitemoor prison in Cambridgeshire he airily called Talk Radio UK to protest his innocence.
