Investigators said a team of undercover narcotics officers from Glendale witnessed a man being robbed in broad daylight at Sylvan Street and Colfax Avenue.
"That's brazen, which means they're capable of violence. And in the end, we see the result, even when the police officers were here, they were not going to comply," said Sgt. Tom Lorenz of the Glendale Police Department.
The two male suspects saw the officers and jumped into a Chrysler PT Cruiser. The officers used their unmarked vehicle to block the PT Cruiser's exit, but the suspect threw the car into reverse and almost hit an officer, who then opened fire.
"When he tried to run that officer down, he also ran that vehicle right into the driver's door of that detective's car, where that detective was standing," said Lorenz.
The driver was shot and taken to a local hospital with non-life-threatening injuries. The second suspect was arrested.
The victim from the robbery on the street is said to be OK.
The two suspects may be responsible for at least six other strong arm robberies in North Hollywood that have plagued the area for a while, said Lorenz.
Glendale police and the District Attorney's Office will investigate the shooting. Los Angeles police detectives from the North Hollywood Division will handle the robbery investigation.
Authorities have not released the names of the two suspects.
