Motorists in York witnessed several emergency services vehicles descend on a busy city road late this afternoon.
Police vans and an ambulance were called out to Foss Islands Road after 4pm on Thursday.

A North Yorkshire Police spokeswoman said the force was supporting a council operation.
She said: “We assisted the City of York Council in executing a warrant regarding concern for the safety of a man on Foss Islands Road.”
Friday update: A council spokeswoman said they would not be able to give a comment owing to the need to protect confidentiality.
