Police shot and killed a Valley Stream man after he allegedly stabbed a student inside a Brooklyn synagogue early Tuesday morning.

The confrontation with police began after Calvin Peters, 49, allegedly barged into Brooklyn's Chabad-Lubavitch headquarters at around 1:40 a.m. and stabbed Israeli student Levi Rosenblat in the head with a 9 1/2 inch knife. Some witnesses reported hearing him say, "I want to kill the Jew."

Officials say an officer fired one shot into Peters' torso after making repeated demands for him to drop his weapon.

Lorraine McCartney was a neighbor to Peters for six years. She told News 12 he was a loving husband and devoted father of two boys.

Police say Peters had been arrested 19 times since 1982 on multiple drug charges and an arson charge.

A lawyer for Peters' family says he had a history of bipolar disorder.

Police say they have every reason to believe this was an isolated incident.

Rosenblat, 22, is listed in stable condition.
