The Department of Public Safety confirms that at least two African American men attacked the deputy at a convenience store on the 24200 block of Sorters Road on Saturday evening.
Both the deputy and his wife fired shots toward the suspects as they fled the scene. Police believe the suspects may have driven off in an early 2000s model red Chevy pickup truck.
ORIGINAL REPORT: Deputy attacked in Porter gas station
It's not immediately clear if the suspects or their vehicle were struck by gunfire.
Investigators say the assault was caught on surveillance footage, which has not yet been released.
"Once the victim leaves the store, the suspect vehicle circles around and pulls up on the side street, where you can see them both exit the vehicle and assault the subject as he's putting ice in the bed of the truck," Lt. John Schmitt with Montgomery County Sheriff's Office said.
