Tayside Police have said a CS canister lost by an officer who was chasing a group of youths has now been traced.
The gas container fell from the officer's utility belt in the St Mary's area of Dundee on Wednesday.
At the time, police warned that the spray was flammable and an irritant. They said it could be dangerous if used by "untrained personnel".
The Tayside force has not disclosed the circumstances in which the CS canister was recovered.
