The unarmed police officer who was stabbed in an attack on West George Street on Friday has been released from hospital, police have confirmed. 

Constable David Whyte was rushed to hospital from the scene after he and five others were stabbed in the attack.

The 42-year-old is the second victim to be released from hospital, after another was released on Tuesday. 

Four other victims remain in hospital for their injuries. Three are in a stable condition and one is "critical but stable".

The others injured were men aged 17, 18, 20, 38 and 53. Two are staff members at the hotel and three are asylum seekers.

Police Scotland Chief Constable Iain Livingston earlier hailed officers' bravery as they rapidly responded to the attack on Friday.

Speaking at a Scottish Police Authority meeting on Tuesday, he said: "Friday demonstrated visibly the officers of Police Scotland once again run into danger to protect their fellow citizens and do their duty.

"I pay tribute to their bravery, selflessness, professionalism and commitment to protecting the public.

"It is disgraceful and deplorable when such attacks take place - and when officers are subjected to violence during the course of their duties.

"And I continue to have an enormous concern about assaults and attacks on police officers.

"I utterly reject any suggestion, any inference, any proposal that being attacked comes with doing the job. It does not."
