POLICE have revisited the scene of the Clutha tragedy as they renewed an appeal for witnesses to come forward in a bid to establish the cause of the helicopter crash.

Officers were at the area around the pub in Stockwell Street, Glasgow, last night - seven days after nine people were killed when a police aircraft crashed into the roof of the building.

Detectives said the helicopter had flown to Gorbals at around 8.47pm that evening before travelling east and was in the sky above Dalkeith at around 9.20pm before returning to Glasgow over Bothwell and Bargeddie. It was seen over Shettleston at around 10.20pm, five minutes before it dropped out of the sky near the River Clyde.

Detective Superintendent Robbie Allan, senior investigating officer, thanked members of the public for sending in photographs and footage of the helicopter and appealed for anyone with more images to contact them.

The Air Accidents Investigation Branch is carrying out inquiries into the cause of the crash and a preliminary report could be released within the next few days. The full findings are not expected for several months.

The Crown Office will then decide whether criminal proceedings or a Fatal Accident Inquiry should be held.

*Road restrictions put in place after the tragedy were due to be lifted at 7am this morning. The closures were put in place to allow the emergency services to respond to the incident.
