MEXICO CITY (AP) — U.S. officials say a Texas truck driver who says he made a wrong turn into Mexico with a trailer full of ammunition has been released from prison but remains in the custody of immigration authorities.

The U.S. Embassy in Mexico said Friday that 27-year-old Jabin Bogan was freed from a maximum security prison in the state of Veracruz. It did not say why immigration authorities were holding him, or when he is expected to return to the U.S., but Bogan likely is accused of violating immigration rules when he entered Mexico.

Bogan's family and lawyers declined to comment. He had faced up to 30 years in prison on an ammunition trafficking charge, but the charge was reduced possession of ammunition after testimony contradicted prosecutors' claim that Bogan deliberately concealed bullets.
