Police in the North are investigating the fatal shooting of a man in the Creggan area of Derry city overnight.
The incident happened just before 1am, but police officers are not believed to have arrived on the scene for a couple of hours.
A local priest says the victim, a young man who lived near the area, was pursued by a number of people before being shot.
There are also suggestions that he may have been delivering a pizza in the area.
The incident happened in a grassy area on the approach to the Creggan estate which has now been sealed off for technical examination.
A local SDLP councillor has said he fears dissident republicans may be behind the shooting as they had been issuing threats against so-called "anti-social" elements in Derry.
Pat Ramsey also said the father of the victim believes his son was killed in a case of mistaken identity.
