Two Guardia Civil traffic officers were injured when their vehicles crashed during a pursuit.
The officers were following a Skoda through the province of Zaragoza for around an hour on Saturday after the vehicle failed to stop at three traffic control points.
The occupants of the vehicle then started to throw items from the car in an attempt to prevent the officers from catching up with them.
The fleeing vehicle eventually crashed into a truck, with one of the patrol cars and a motorbike being damaged in the collision.
Upon approaching the crashed car, officers discovered that the driver, a Polish national, was naked from the waist down and it was his clothes he had been throwing from the vehicle.
One of the officers suffered a broken leg and the other from a collapsed kneecap. The reckless actions of the driver risked the lives of many people on the roads and will be dealt with through the courts.
