Man Injured after Bomb Planted in Truck.

DALTON, Ga. (AP) -- A man connected with a motorcycle gang was airlifted to Erlanger hospital in Chattanooga early Thursday after a bomb in his truck exploded.

Police believe a rival motorcycle club planted the bomb in the truck of James Wayne Brock Jr., 27, in retaliation for the death of a gang member. He was getting into his truck to go to work at a local carpet mill when the bomb went off, said Capt. Rick Swiney with the Whitfield County Sheriff's Office.

His two sons saw the explosion as they waited for the school bus, Swiney said.

Hospital officials declined to release his condition.

Neighbors said the explosion sounded like a sonic boom.

"One of his sons asked me, 'Did you see what happened? My daddy got blew up.' I just kissed him on the head and told him it would be all right," neighbor Sarah Gentry said.

The Georgia Bureau of Investigation is helping with the probe into the incident. GBI Special agent Jerry Scott said the bomb was not a random act but was targeted specifically at Brock.

Brock, who is affiliated with the Renegades motorcycle club, was part of a June 24 shootout with rivals the Outlaws in the parking lot of a Clayton County strip club, according to Forest Park police. Outlaws member Frank Rego Vital, 44, was killed during the gunplay.

Brock's father, James Brock, was arrested in Dalton in January on aggravated assault charges for firing a shot into the ceiling of a bar during a fight with rival gang members. A bullet fragment from Brock's gun hit a man in the leg, causing minor injuries.

He has been denied bond and remains in the Clayton County jail.
