Authorities in Arizona are checking out another possible shooting on a Phoenix-area freeway.

The state Department of Public Safety says officers are responding to a report of a damaged window on a vehicle that was traveling on Interstate 10 Thursday morning.

Trooper Tim Case says a "projectile" hit the window but no shooting has been confirmed.

Video shown by KNXV-TV showed an intact rear window with a visible indention.

This follows 10 shooting incidents in which the DPS says either bullets or projectiles hit vehicles in the past two weeks. All but two were on I-10.

DPS says seven of the 10 shooting incidents involved bullets and the other three were unspecified projectiles.

No serious injuries have been reported.
