Police say a man just released from Twin Towers jail in downtown Los Angeles jumped out of a moving ambulance, hid out in a church, then stabbed a police officer before police shot and killed him.

Police spokeswoman Norma Eisenman says the man was freed Saturday afternoon and attacked medics taking him to a hospital in a private ambulance.

Commander Andrew Smith tells the Los Angeles Times the man jumped out of the ambulance and ran into a church in Boyle Heights.

Smith says as officers searched the church with a dog, the man stabbed one of them through the bicep with an 8-inch knife. He says at least one officer then fired and killed the man.

Eisenman says the officer is in a hospital and is expected to survive.
