A 22-year-old man was arrested for the possession of an illegal firearm in Lower Crossroads yesterday.
Metro police officers, who were conducting a by-law enforcement operation in the area, stopped at a carwash to speak to staff about water usage.
They then spotted the man who ran away soon after noticing the officers.
They gave chase and caught up with the suspect as he tried to discard a 7.65 pistol with its serial number filed off and an empty magazine.
The man was detained at Philippi East police station.
