A suspected drunk driver Saturday crashed into the back of a Louisiana State Police squad car on Interstate 10, causing significant damage to both vehicles.

A trooper was stopped on the shoulder of Interstate 10 east near La. 44 when the driver rear-ended his squad car, said Trooper 1st Class Jared Sandifer.

The trooper suffered minor injuries, as did the driver and a young passenger, Sandifer said.

The crash remains under investigation and charges are pending, he said.
