A 32-year-old man has been shot and seriously injured in Donaghmede in Dublin.

The shooting happened near a creche on Holywell Avenue at around 9am.

It is believed the man was shot once in the head after he dropped a child at the creche.

He was taken to Beaumont Hospital, where he is in a critical condition.

Gardaí believe the attack was carried out by a lone gunman, who left the scene on foot.

The scene has been preserved.

Gardaí are seeking to identify witnesses and are appealing for anyone with information to contact them.

The man is known to gardaí as a dissident republican.

He had been warned by officers that his life was in danger after a previous shooting.

He was an associate of former Real IRA leader Alan Ryan, who was shot dead in Dublin in 2012.

The man is wanted by the PSNI for questioning about the murder of two men in Belfast in 2007.
