Oakland and BART police officers shot and killed a man Saturday morning near the Fruitvale BART Station when, authorities said, he charged the officers holding a knife in each hand after leading them on a chase for blocks.

Five officers opened fire on the man when he threatened an officer after police unsuccessfully tried to subdue him with a Taser stun gun, Oakland police Officer Jeff Thomason said.

"He had one knife in each hand and charged toward one of the officers," Thomason said. "That's when the other officers opened fire."

Three Oakland officers and two BART officers fired their weapons, police said. The man, who has not been identified, was pronounced dead at the scene.

The Oakland officers have been placed on paid administrative leave, the department's standard practice after an officer-involved shooting. The BART officers were expected to be put on paid leave also, said BART spokesman Linton Johnson.

The incident began at about 8:15 a.m. when a 911 caller alerted Oakland police to a man with a knife in the 3200 block of East 12th Street, several blocks from the Fruitvale BART Station, police said.

While Oakland officers were en route, a dispatcher notified BART police because of the man's proximity to the station, Thomason said.

BART officers were the first to find the man, who Thomason said appeared to be 30 to 40 years old.

When the BART officers approached, at least one witness said the man called out, "Shoot me, shoot me, shoot me," Thomason said. Then the man took off running, he said.

The man led police on a chase for blocks, including running north on 34th Avenue past St. Elizabeth High School, police said. An Oakland officer fired his Taser at the man on 34th Avenue, but he kept running, Thomason said.

After the man doubled back on 33rd Avenue, Oakland police again unsuccessfully tried to subdue him with a stun gun, Thomason said. That's when the man charged an officer, whose colleagues opened fire, police said. None of the officers was injured in the shooting, which occurred in the 1500 block of 33rd Avenue.

Investigators believe there is no connection to the highly publicized Jan. 1, 2009, shooting of unarmed train rider Oscar Grant by BART police Officer Johannes Mehserle at the Fruitvale BART Station.

Grant was killed as he lay facedown on the platform. The shooting touched off widespread protests in Oakland, which resurfaced after a Los Angeles jury convicted Mehserle of involuntary manslaughter July 8 instead of a more serious murder charge.
