A man shot dead by an off-duty police officer during a suspected filling-station robbery has been named.
Investigators are looking into claims that 29-year-old Marc Alexander Ringland was armed with a knife when he was shot at the premises on Belfast's Albertbridge Road.
Mr Ringland was from the east of the city - the same district where the shooting took place at around 7pm on Thursday.
The man's identity was confirmed by the Police Ombudsman's office, which is investigating the circumstances of the fatal shooting.
A total of 20 ombudsman investigators are probing the shooting, which took place in a busy shop at a petrol station on a main route running into the centre of the city.
A spokesman for the Ombudsman's office said: "The area was cordoned off to allow forensic examination to take place and a number of items have been retrieved for further analysis, which is ongoing today. We have also identified and spoken to a number of witnesses, and would like to appeal for anyone else who may know anything about what happened to contact us."
It is thought the off-duty officer may have come upon the scene, but the Police Service of Northern Ireland (PSNI) said the full details of what happened have not yet been established.
PSNI officers are routinely armed while on duty and have weapons for their protection when off duty.
Sinn Fein representative for the area Niall O Donnghaile said: "Regardless of the circumstances surrounding this incident, we are dealing with a fatality. Our thoughts are with the family of the man who has been shot. While there has been an increase in robberies in south and east Belfast over recent weeks, it is vital that tonight's incident is investigated fully and that all information comes to light."
Assembly member for the area Dawn Purvis also called for a full investigation.
