The chief constable of Police Scotland has paid tribute to the officer who was injured during a stabbing incident in Glasgow.
Constable David Whyte was critically hurt - and five others were also injured - when a man started attacking people at the Park Inn hotel in the city centre yesterday.
In a statement, Chief Constable Iain Livingstone said: "Terrible incidents such as we have seen are, thankfully, very rare in Scotland. This event has understandably shocked the people of Glasgow, and indeed, the whole country.
"My thoughts and very best wishes are with those who have been injured and their families, including our colleague Constable David Whyte who was seriously injured in the course of doing his duty. I offer my personal support to all those affected.
"Officers have once again run into danger to protect their fellow citizens. Their professionalism as police officers was outstanding. I pay tribute to their bravery, selflessness and commitment to protecting the public.
"I briefed the first minister and the prime minister on the circumstances and advised them both that we are not treating the attack as a terrorist incident.
"It is essential enquiries are now carried out to establish the full circumstances and all speculation must be avoided."
He added: "Scotland is a safe place to live and work. We have cohesive communities who work with their police service to maintain our peaceful and respectful way of life.
"In the context of the current health emergency, and to respect those injured today and the people of Glasgow, I ask everyone to exercise personal responsibility. Please, do not gather in crowds this weekend."
