Prison officer Adrian Ismay, who was injured after a bomb exploded under his van in East Belfast, has died in hospital. The officer was on his way to work at Hydebank Wood Young Offenders Centre and Prison when the bomb detonated on March 4th. The 52-year-old was rushed to hospital where his injuries were described as serious but not life-threatening. However, sources told Belfast Live that it is believed he suffered a heart attack in recovery.

I'm devastated. Can't believe the news. I was texting Adrian before we left for the US. He was doing well. My thoughts are with his family.

In a joint statement justice Minister David Ford MLA and NIPS Director General Sue McAllister said: “Adrian Ismay gave over 28 years of service to prisons in Northern Ireland and he was greatly respected by all those who knew him. "Our thoughts and prayers are with his family, friends and colleagues at this difficult time.” East Belfast Ulster Unionist MLA Andy Allen said: “This is devastating news and my heartfelt sympathies are with the prison officer’s family. We must ensure that all necessary support and assistance is given to the family at this difficult time. “The people responsible for this despicable attack must be brought to justice. “I would again reiterate that the people responsible do not represent wider society.  They cannot and will not be allowed to take this society back to the past.” Amid reports that a dissident group named the 'New IRA' have claimed responsibility, authorities have warned for vigilance ahead of the 1916 centenary celebrations. Deputy Chief Constable Drew Harris issued a stark warning from PSNI headquarters on March 4th. He said: "I believe that there are people within the dissident republican groupings who want to mark this centenary by killing police officers, prison officers and soldiers.
