Two men have been arrested by detectives investigating the murder of a father outside a school in Belfast last year.
Jim Donegan, 43, was shot dead as he waited to collect his 13-year-old son from St Mary's Christian Brothers Grammar School in west Belfast on 4 December.
Detectives said the same killer had been waiting for his victim at the scene five days earlier, but Mr Donegan did not pick up his son that day.
Suspects aged 53 and 39 were detained at Musgrave police station in Belfast today under anti-terrorism legislation, a PSNI statement said.
Investigators have linked the killing to the Irish National Liberation Army.
Mr Donegan was gunned down in front of schoolchildren and parents.
He was shot eight times with a semi-automatic handgun.
