Update: 11:50 a.m. - A man has been arrested following the 'suspicious device' incident Friday night at a St. Pete intersection. 

Police arrested Andrew Bryant, 37, on 2 counts of possession of a controlled substance, 1 count carrying a concealed weapon, 1 count possession of drug paraphernalia.

The suspicious device was confirmed to be a homemade device to make narcotics, not an explosive device, police said. 

Original Report: A major intersection in St. Petersburg is back open after a police investigation involving a suspicious suspect in a car and a possible suspicious device.

Police shut down Tyrone Boulevard, 22nd Avenue N and 66th Street after getting a call about a man inside a vehicle in a McDonald's parking lot for about five hours.

Police say the man did not make sense when they tried to talk to him, and he appeared either ill or under the influence. 

Officers say they saw a backpack that was suspicious enough to order an evacuation of everything around a 1,000-foot radius. 

The Tampa Bomb Squad blew up the device. No word what it was.
