Investigation into murder of police constable in north Belfast continues

An investigation into the murder of a police constable in north Belfast 30 years ago is continuing, police have said.

Constable John “Jackie” Haggan was shot dead while socialising at the Dunmore Greyhound Stadium in north Belfast on March 10, 1994.

The 33-year-old father-of-two and his wife from Newtownabbey had been expecting their third child at the time.

Three men, aged in their 50s, were arrested by detectives from the PSNI’s Legacy Investigation Branch on Thursday under Section 41 of the Terrorism Act on suspicion of murder and membership of a proscribed organisation, at addresses in Belfast and the Newtownabbey area.

They were released on Friday.

A 50-year-old man was also arrested in connection with the investigation on Tuesday. He has since been released following questioning.

A PSNI spokesperson said the investigation continues.
