California Highway Patrol officer shot, bystanders detain suspect and provide trooper aid

A California Highway Patrol officer was shot on Interstate 8 while investigating a traffic collision near Mission Valley in San Diego Wednesday evening.

CHP Captain Michael Harris said during a press conference that the officer "was investigating a traffic collision when he became involved in a struggle with a pedestrian, resulting in a single gunshot," according to Fox 5 San Diego.

Good Samaritans helped subdue a 25-year-old male suspect and provided aid to the trooper. A video of the bystanders' heroic efforts was posted to social media on Thursday. One group of men appear to be holding the suspect at knifepoint while another group renders aid to the officer. California Highway Patrol troopers arrived on scene shortly after.

Harris said that the suspect is currently in custody and will be booked on appropriate charges "once they are explored and determined," Fox 5 San Diego reports.

The unidentified male officer was transported to Scripps Mercy Hospital and is said to be in stable but serious condition. He is recovering from a gunshot wound to his right thigh, according to Harris.

This is a developing story.
