A MAN has been shot dead in a city centre flat.
Police and ambulance crews attended the first-floor apartment, above business premises in Shipquay Street, close to the Diamond area of Derry city.
Emergency services were alerted at around 11am and the scene was cordoned off.
SDLP Assembly member Pat Ramsey said people were stunned. He said: "There is a sense of bewilderment and awfulness. This happened right in the heart of the city."
The incident comes a day after a man in his 40s was found murdered in a lake in north Belfast.
A woman who was with the victim at the time of the shooting in Derry was taken away by paradmedics in a distressed state. She was uninjured.
At one stage there were three ambulances outside the flat.
Derry is the current UK City of Culture and, even though it is a major base for dissident republicans, it has been largely free of any major terrorist incidents since January.
Mr Ramsey: "What we don't need is murderous gangs running around causing mayhem."
Deputy First Minister Martin McGuinness blamed dissident republicans motivated by criminal intent for the murders in Belfast and Derry, his home city.
He said: "Many of these gangs are involved in the drug trade themselves. They are routinely extorting money from drug dealers and other criminals. They are heavily involved in all sorts of organised crime. Yet they carry out murders like the ones we have witnessed in Belfast and Derry under the bogus notion that they are standing up for the community.
"The community have already made their stand. They have stood against gangsterism and criminality and stood for peace and building a new future. The community now need to work with the PSNI to bring forward information to allow them to tackle criminality and the criminal gangs who seek to profit on the backs of ordinary decent people."
