A post-mortem is to be carried out this afternoon on the body of a former Real IRA chief killed in Cork city.
Aidan O'Driscoll (37) was shot repeatedly at around 5pm yesterday evening in the Blackpool area.
He was later pronounced dead at Cork University Hospital.
The Ballyvolane native had links to the Real IRA and this will form a major part of the murder investigation - but Superintendent Michael Comyn says it is still early days.
"Mr O'Driscoll is a son, a father and we will be using all of our resources to solve this," he told reporters.
A post mortem will be carried out this afternoon, and the scene of the shooting has been preserved.
