Inmates taunt prison officers over the death of Adrian Ismay
Prison officers have reported being goaded by inmates about the death of their colleague, Adrian Ismay.
Mr Ismay, a father of three, was the victim of a bomb attack by dissident republicans on March 4.
He died yesterday of a heart attack and the police are yet to determine whether or not they are to treat the 52-year-old's death as murder.
Mr Ismay had been travelling in a blue van on his way to work at around 7am when a bomb exploded under his vehicle.
A group calling itself the 'New IRA' later claimed the attack.
Mr Ismay worked at Hydebank Young Offender's centre in South Belfast and helped train prison officers to work at HMP Maghaberry.
Flowers were left at the scene of the bomb attack yesterday
It has been reported that when news of the death of Mr Ismay, who was described by colleagues as a "decent man", got through to republican inmates at Maghaberry, some lit cigars and goaded officers.
Mr Ismay's fellow prison officers said they would now press the police to treat his death as murder.
DUP MLA, Paul Givan, said: "Adrian's colleagues see this as murder. A bomb was placed under his vehicle. The intent was to murder. He had a heart attack within days. Most people will be expecting that this will be a murder investigation."
One man, Christopher Robinson, 45, appeared in Belfast Magistrate's Court last week charged with attempted and with possessing an improvised explosive device with the intent to endanger life.
