A 13-year-old runaway out of western Alabama was struck with a Taser stun gun and taken into custody Wednesday morning after police found him with a handgun in a Birmingham neighborhood.

The incident happened about 8:20 a.m. in the 6600 block of Avenue M in the Green Acres neighborhood. Sgt. Johnny Williams said West Precinct officers were called to the area on a report of someone with a gun.

When officers arrived in the neighborhood, they spotted two young males - ages 13 and 15 - that matched the description called into Birmingham police. An officer told the teens to put their hands up, but Williams said the 13-year-old instead reached into his pocket.

That's when police used the stun gun on the juvenile. He was taken into custody and handcuffed. Williams said the 13-year-old had a .38-caliber handgun in his pocket.

The juvenile, he said, is a Department of Human Resources runaway from Woodstock, Al. His case will be handled through the juvenile court system.

The 15-year-old, Williams said, was not armed. His parents were called to the scene and he was turned over to them.

The investigation is ongoing.
