An elderly prison inmate has been charged with murdering a fellow prisoner inside a Sydney jail on Monday night.

NSW Police told The Huffington Post Australia on Tuesday morning a 71-year-old man died inside Long Bay jail, at Malabar in Sydney's south, around 11pm on Monday after "an alleged assault".

Later on Tuesday, police announced that a 77-year-old man had been charged with murder after an assault inside one of the prison cells. The younger man was found inside with "serious head injuries", and despite correctional officers providing first aid, the man died after being transported to hospital.

"A 77-year-old inmate was detained by correctional officers, before being arrested by police from Eastern Beaches Local Area Command and taken to Maroubra Police Station," police said in a statement.

"Following inquiries by local detectives and the State Crime Command's Homicide Squad, the older man was charged with murder."

The accused was refused bail and will appear at Parramatta Bail Court on Wednesday.

"A crime scene was established and examined by specialist forensic officers. A number of items have been seized from the cell," police said.

Fairfax Media reported the man was bashed with a sandwich press.
