EIGHT prison officers have been suspended on suspicion of smuggling mobile phones into a top security jail in West Yorkshire, sources have said.

An investigation is under way at Wakefield jail, which holds some of the country’s most dangerous offenders.

It was launched last October into an alleged phone racket at the category A jail.

West Yorkshire Police confirmed they are investigating the allegations but said no arrests have been made.

A spokesman said: "Police are liaising with prison authorities in relation to allegations against a number of members of staff and inquiries are ongoing."

Police said the allegations relate to offences under the Offender Management Act.

According to reports the officers face allegations of smuggling after mobile phones, top-up cards and receipts were found in a bag of sugar.

Wakefield is an all-male high-security prison and holds more than 700 inmates.

Former inmates include child killer Ian Huntley and serial murderer Harold Shipman.
