Between six and eight devices were made safe by the Army tonight after loyalist killer Michael Stone stormed Stormont’s parliament buildings during an Assembly debate.
The North’s chief constable, Hugh Orde, said they were “viable” devices.
He said their potential for causing damage, death and injury was being assessed.
He added: “They are fairly amateurish in design, that does not make them any less dangerous.”
Orde, speaking at a press conference at police headquarters just over a mile from Stormont, said a gun and a knife had also been recovered.
Stone was being questioned by police tonight about what the chief constable branded “a sad publicity act by a very sad individual”.
