Two prisoners at the HM Prison Frankland in Durham County have been charged with killing a fellow inmate who was jailed for raping a 13-year-old girl.

The two men, aged 32 and 23, will be produced before the magistrates Monday for the death of Mitchell Harrison, 23, who was serving an indeterminate sentence for the rape of a 13-year-old girl, according to a report in The Guardian.

Harrison received the indefinite sentence, with a minimum of four-and-a-half years, at Carlisle Crown Court in January 2010. He was also placed on the sex offenders' list for life. The girl was assaulted in Kendal, Cumbria, in August 2009.

According to postmortem reports, Harrison, who was from Wolverhampton, died of multiple injuries.
