The officer had been the target of an explosive device attached to his vehicle in East Belfast on March 4. He passed away today (Tuesday) in hospital.
“My deepest sympathy is with the officer’s wife and loved ones, and my thoughts and prayers are with his colleagues following this devastating and tragic news,” said Mr Lyttle.
“The entire community must show support for our prison officers and others who keep us safe. The vast majority of people will show revulsion for the actions of those behind the attack on this officer. We must redouble our efforts to ensure their culture of terror will not be allowed to return.
“I would again urge anyone with information about the incident which has now claimed a life to contact police immediately and ensure these evil people are brought to justice.”
