A man has been arrested over the murder of a convicted criminal in north Belfast.
The 36-year-old was detained on Tuesday evening and remains in custody, police said.
Dubliner Robbie Lawlor, 36, was gunned down outside a house in Etna Drive on Saturday.
Lawlor had previously been linked with the murder of teenager Keane Mulready-Woods in Co Louth in January.
Four other men who were being questioned have been released without charge.
