WOODLAND HILLS, Calif. (KTLA) -- A $100,000 reward is being offered for information leading to the arrest and conviction of the man who shot and wounded a LAUSD police officer outside El Camino High School in Woodland Hills.

City Councilman Dennis Zine announced the reward Friday for information leading to the arrest and conviction of the man who shot Officer Jeff Stenroos.

In the meantime, police have released a sketch of the gunman.

The search for the suspect was called off for the night late Wednesday, but deputies promised the investigation would continue until they made an arrest.

The shooting was reported around 11:30 a.m. Wednesday near near Manton Ave and Burbank Blvd, east of the high school campus.

Stenroos, an eight-year veteran of the LAUSD police force, was taken to Northridge Hospital Medical Center for treatment.

According to LAUSD spokesman Robert Alaniz, the officer was shot in the chest, but he was wearing a protective vest.

"He is a lucky man. The vest did its job and stopped the bullet," said Dr. Stephen Jones at Northridge.

Stenroos was released from the hospital after undergoing a large battery of tests to make sure he was uninjured except for a large bruise on his chest below his collar bone.

The officer was shot after he confronted a man he witnessed breaking into cars near the high school campus, according to Los Angeles Police Chief Chief Charlie Beck.

When Officer Stenroos confronted the man, the suspect pulled a gun and fired several rounds, striking Stenroos at least one time.

Los Angeles Police Chief Charlie Beck said the officer fell back and hit his head, but was able to stumble to his patrol car, where a civilian helped him radio for help.

A 12-block area around El Camino Real High School was sealed off most of the day and some 9,000 students from schools inside the containment area were on lockdown for hours without food or access to restrooms.

Hundreds of officers from the LAPD, school police, the L.A. County Sheriff's Department and the California Highway Patrol surrounded a large area around El Camino High School throughout the afternoon, cordoning off a seven-square-mile area. Firefighters called to the scene wore body armor.

The perimeter stranded thousands of people who were unable to return to their homes.

The suspect, described as a white man in his 40s wearing blue jeans and a bomber jacket, fled and was last seen running east on Burbank Boulevard.

The attack occurred just one day after an accidental shooting wounded two students at Gardena High School.
