LAPD shooting: Two undercover detectives were injured when a shooter ambushed them on their way back to an LAPD police station.
A black-clad gunman ambushed two undercover detectives returning to a police station early Tuesday, but their wounds didn't prevent them from aiding the hunt for the attacker.
Police Chief Charlie Beck described the shooting as an attempted assassination and mobilized a huge search involving helicopters, dogs and about 200 officers.
Police initially cordoned off 25 square blocks of the Mid-City area of Los Angeles, leaving thousands of residents stranded in homes and forcing drivers to find detours for their morning commutes.
Later in the day, the search focused on a neighborhood just south of the LAPD's Wilshire substation, where the attack occurred.
At least 10 people were detained for questioning and released. Police also planned to look at surveillance video from homes and businesses.
"Anybody who's willing to do this and take on two armed police officers outside of a police station is obviously a very dangerous person," police Cmdr. Andrew Smith said.
