A 24-year-old prisoner has been charged with the murder of an 80-year-old Derbyshire man.
David Peter Gomersall has appeared in court charged with the murder of John Coxall.
Mr Coxall, of William Street, Long Eaton, was found unresponsive in his cell at Nottingham Prison last Thursday.
He was declared dead at 5pm and Gomersall, who, like Mr Coxall, was a serving prisoner, was arrested.
A spokesman for Nottinghamshire police said: "David Peter Gomersall, 24, has been charged with the murder of John Coxall.
"The cause of death was strangulation.
"Gomersall appeared at Nottingham Magistrates' Court on Saturday, December 5 and then at Nottingham Crown Court on December 8.
"A plea and case management hearing will be on March 14, 2016, with a trial set for May."
Mr Coxall was serving a 30-week jail term after pleading guilty to twice breaching the terms of a restraining order on September 1 and October 6.
It is understood the breaches were in relation to contacting a neighbour when he had been banned from communicating with her.
In December last year, he was jailed for six months for the same offence after breaching a previous order eight times.
