Officers have named four of the eight people who died when a police helicopter crashed into a crowded pub in Glasgow.
PC Kirsty Nelis, 36, PC Tony Collins, 43, and civilian pilot David Traill, 51, were killed when their aircraft smashed through the roof of The Clutha pub, in Stockwell Street, on Friday night.
Five people who were watching a ska band in the pub also died when the ceiling caved in, filling the venue with choking dust.
Only one of them has so far been named - Gary Arthur, 48, from Paisley.
Friends of a man called Mark O'Prey have been tweeting pictures of him, saying he is missing and was drinking in the pub on Friday night.
Many of PC Nelis' friends have changed their Facebook profile pictures to a black square cut across by a thin blue line in her memory.
Andrina Romano said: "For my beautiful friend Kirsty and all others involved. You will never be forgotten and I will miss you every day. Rip."
The mangled wreckage of the helicopter remains embedded in the middle of the building. It is not known how many people are still inside the pub.
Police Scotland Chief Constable Sir Stephen House told a news conference he "couldn't discount the possibility" that the death toll will rise.
Earlier, Deputy Chief Constable Rose Fitzpatrick said: "Until we remove the helicopter, we cannot be sure what we'll find."
Officers have removed a second body from the wreckage, and are continuing the formal process of identification.
DCC Fitzpatrick said it was a "painstaking" recovery operation because they had to ensure the safety of the emergency services at the scene.
A service for the victims was held at Glasgow Cathedral on Sunday morning, with Scottish Justice Secretary Kenny MacAskill and Deputy First Minister Nicola Sturgeon among those attending.
The Prince of Wales and the Duchess of Cornwall have sent their "most heartfelt thoughts and sympathy to the families of those who were lost or injured in Friday's truly shocking helicopter accident in Glasgow".
