Mountjoy alert: 'Cannabis grinder' mistaken for revolver triggers lockdown at Ireland's largest prison
A cannabis grinder mistaken for a revolver hidden above a door triggered a massive security lockdown at Ireland's largest prison.
Mountjoy Prison was subjected to the lockdown this afternoon after inmates had their lunch.
An item - which was feared to be revolver - was found above a door in a 'service area' of the prison.
This area is not frequented by the prison population, and no cells are located there.
It was initially feared that a revolver and a quantity of ammunition was found.
This sparked a lockdown of Mountjoy Prison as staff conducted a full search of the complex.
However, upon closer inspection, it was found the item was a "cannabis grinder".
It's understood the discovery was made shortly after the inmates had lunch and were locked in their cells as is normal practice.
They remained in their cells for the duration of the search.
A spokesman for the Irish Prison Service said the circumstances surrounding the find were still unclear.
