A Texas inmate has taken a ride on the roof of a police car after clambering out of the window.
Martin Gregory Estrada, 31, was being transported between facilities when he slipped from his handcuffs, shattered the passenger window, and climbed onto the roof of the car.
The inmate managed to balance himself on the top of the vehicle, and the officer continued driving until the help he had summoned arrived.
A video taken by other motorists shows the man sitting on the moving car, then leaping from the roof as it slows and is approached by other vehicles.
He is then apprehended by the arriving officers.
Authorities said that Estrada was being transported 150 miles (241km) from a hospital facility where he had allegedly assaulted someone.
He is now being held on charges including escape and unauthorised use of a vehicle.
