Officers were called to Haleforest Grove, in Stockbridge Village, on Wednesday after reports a man had been seen at a house with a gun.
At around 12.40pm police forced their way into the home before setting up a cordon on the street.
A short time later, a member of the public was videoing the scene when a man in a bright orange tshirt was seen running through the street from police.
