Investigations are ongoing into reports of shots being fired in Derry on Friday night.
A man was seen in the Gartan Square area carrying a black gun at around ten past ten on Friday night.
Police say a short time later, two loud bangs, believed to be gunshots, were heard in the nearby area.
They believe the gun was fired by the suspect – though there are no reports of any injuries.
He was wearing a black-hooded jumper and is believed to be aged between his late 30s and early 40s.
Detectives are appealing for information.
