Officers are chasing a motorcycle rider Monday in the Rancho Cucamonga area. The rider is wanted in connection with a shooting that injured a San Bernardino County Sheriff's deputy in Rancho Cucamonga, authorities said.

The suspected cop-killer slammed into the back of a sedan — sending him cartwheeling through the air and skidding onto his back before the bike rolled over him.

Deputy Andrew Nuñez leaves behind a wife and a 2-year-old daughter. His wife was also expecting, the sheriff said.

A man accused of shooting and killing another man last week in LA was arrested after police on-scene engaged in a foot pursuit and used less-lethal rounds against him.

A former Los Angeles Police Department officer who fatally shot an unarmed homeless man in Venice in 2015 was behind bars Friday following his arrest at Los Angeles International Airport. Clifford Proctor, now 60, was arrested at the airport Thursday, according to police and jail records. He was being held in lieu of $2 million bail.

Officers from the Bell Police Department shot the man multiple times before he drove away and started the pursuit.

The scene became more tense as LAPD officers moved in with guns drawn. The man was making odd gestures and there were times he pointed the gun at his head. He fell to the ground after he was struck by the less-lethal rounds. Officers swarmed him and made the arrest.
