Mountjoy put in lockdown after prisoner climbs onto roof to retrieve suspected drugs
Prisoners at Mountjoy jail were locked in their cells for several hours this afternoon after one inmate climbed on to a roof in a bid to retrieve contraband.
Shortly after 11am the criminal scaled a wall in the D division of the jail on Dublin's North Circular Road and made his way onto a roof.
He remained there for four and a half hours while trained negotiators were drafted in to speak with him.
A prison source said all other inmates have been locked in their cells while the standoff took place. Shortly before 4pm he agreed to come down.
"This was a dangerous situation. Those walls are quite high and it would appear he went up there to collect contraband.
"The negotiators reasoned with him. He came down shortly before 4pm."
The source continued: "Prisoners were locked in their cells at lunch and they were not released until the man came down. This understandably caused some anger as a number of visits were cancelled."
A spokesman for the Irish Prison Service said the inmate will be subject to disciplinary action.
Last month 35 prisoners in Mountjoy were locked into a yard after an attempt to smuggle drugs into the jail went wrong.
The incident happened shortly after 11am on July 31 when an inmate was discovered on the roof trying to retrieve a large package of drugs.
He was intercepted by prison officers but managed to throw the contraband into the exercise yard before being removed from the roof.
