A San Diego bomb team detonated a destructive device inside a vehicle's trunk in the Morena area Thursday evening.
San Diego Police were tipped off to a suspicious situation when they stopped a man and woman walking on Pacific Highway around 4:10 p.m.
During the officers' interaction with the couple, the woman was arrested for possession of a controlled substance, the SDPD says.
Police had reason to suspect something was not right inside the man's vehicle, so they searched it where it was parked near Anna Drive and Pacific Highway.
Inside the trunk, they found what police will only describe as a destructive device.
San Diego Fire-Rescue's bomb squad was called in to investigate and ultimately detonate the object.
The man was arrested for possessing the device.
