Closures after white powder alert in Manchester
An accident and emergency department and police station in Manchester had to be closed, after two men came into contact with an unknown white powder.
One man arrived at North Manchester Hospital at about 1530 BST. The second went to Collyhurst police station at 1600 BST.
The fire service closed both until about 1800 BST as a precaution.
They were reopened after specialist officers found the powder was non-hazardous, a spokesman said.
Thrown at car
He said ambulances had been diverted to other accident and emergency units.
There were about 20 people in the department at the time, who were asked to remain where they were, he added.
Police also received reports that someone came into contact with an unknown substance in Jersey Street, Ancoats, at about 1430 BST.
And another man had white powder thrown at his car in Blueberry Avenue at about 1730 BST, police said.
Police are investigating whether there is a link between the incidents.
