CLEARWATER, Fla. (AP) - Two teenage brothers thwarted a would-be robber by wrestling a gun from him and locking him inside a southwest Florida convenience store.

According to a police report, the brothers became suspicious when the man adjusted his waistband and they noticed something sticking out. They were ready when Clarence Lampkins allegedly pulled the gun and Ali Ateia was able to wrest it from him Saturday night.

Ali and his brother, Haidar, then locked Lampkins inside their family's store until police came.

Lampkins is charged with carrying a concealed firearm, possession of cocaine, robbery, felonious possession of a firearm, battery and possession of a firearm while committing a felony.

He was being held on $77,500 bail at the Pinellas County jail. It's unclear if he has an attorney.
