The PSNI is searching for a suspect in his forties after a man was shot dead outside a Belfast school yesterday.
The suspected gunman was wearing a hood and a high-viz vest with "security" written on the back.
The victim was shot a number of times outside St Mary's Grammar School in the west of the city.
PSNI Chief Superintendent Jonathan Roberts says children could have been killed: 'A disgraceful and reckless act for which there can be no justification whatsoever. The act was carried out in the immediate vicinity of three schools and it is entirely possible that we could have had a seriously injured or dead child or children as a result of this terrible act'.
