A man ripped out a rose bush and damaged a paramedic response vehicle at the North Bellmore firehouse on Aug. 12 amid $1,500 in vandalism, authorities said Thursday.

Surveillance cameras also show the man putting out his cigarette butt on the door of the department’s vehicle and dumping a bucket of sand onto the hood at the Newbridge Road firehouse about 4:15 a.m., said John Caluori, superintendent of the North Bellmore fire department.

“The question I had was why,” Caluori said. “He was just walking past and all of a sudden vandalizes the vehicle.”

Nassau police also released footage of the man at a convenience store, which Caluori said was a 7-Eleven two blocks away. Another photo showed cement pavers scattered around.

The firehouse videotape captured the man setting down his plastic grocery bag, dumping the bucket of sand that served as an ashtray, then ripping out the bush.

Caluori said the paramedic vehicle had scratches and other damage and will have to be out of commission for about two days for repairs.

First Precinct detectives said anyone with information can call 516-573-6156.
