SAN ANTONIO (KTSA News) — The San Antonio Police Department is investigating a crash on I-35 that may have involved human smuggling.

Investigators say a pickup truck side swiped an unmarked police car near Fischer Road before 8 a.m. Wednesday morning. The driver was an off-duty SWAT officer who chased the truck after it failed to stop.

Police say after the driver of the truck pulled over, several people jumped out of the cab and bed of the truck and ran off.

Officers search the area but found none of the people believed to have run away from the truck.

KSAT reports the driver could be facing charges beyond hit and run if the people who ran away are found.
