Tennessee ? Somebody hijacked a truckload of rodeo bulls bound for a professional bull riding show, then abandoned them after running out of gas, authorities said.

The truck and its cargo were found early Saturday with an empty gas tank in the outskirts of Nashville, police said. The bulls – about a dozen valued at $100,000 – were unharmed. A suspect had not been arrested.

Police Sgt. Robert Durbin said the animals were being delivered to Nashville’s Municipal Auditorium for the show when the thief jumped into the cab late Friday.

A woman in the truck escaped despite the carjacker’s attempts to keep her inside, witnesses said.
