A threatening note left on a car at Bunker Hill Community College prompted a bomb scare yesterday afternoon that closed down a large portion of the parking lot, police said.

The car — a blue Honda Civic sedan — is owned by a Revere man who said he was visiting the school for an orientation.

“I was here for a tour. When I came out I saw a note on my car. It said ‘Don’t start your car if you want to live,’ ” he said.

The man said the note was handwritten in pencil on a white piece of paper. He said he took the note to police. He told the Herald he doesn’t know anyone at the school and does not know why anyone would want to do him harm.

“I have no idea why someone would want to do that,” he said. “It’s a little scary.”

The state police bomb squad responded to the scene and cleared the car after finding nothing hazardous, police said.

The prospective student said he planned a general studies curriculum for the fall, but now he’s not so sure if he wants to attend the school.

“I don’t know,” he said. “I’m thinking about it.”

A combination of state police and campus police roped off a large section of the parking lot with yellow police tape as they investigated. State Police Bomb Squad technicians cleared the car, leaving the hood up and the doors open. Investigators took the note, the man said.

A woman watching the activity said she was shaken by what happened.

“Something like this,” she said. “It’s crazy. I’m glad everyone is OK.”
