Police were called out to a car in a Leeds street this afternoon after a member of the public reported spotting a firearm.
But when armed officers arrived on scene they found an 'air weapon' in a nearby property which police believed to be the gun which had been reported.
The incident happened on Belle Isle Road at 1.40pm.
The air weapon was not seized and no arrests were made.

"Officers attended and made enquiries during which an air weapon was found in a nearby property which is believed to be the sighted weapon.”
