A fire at a Baldwin home was intentionally set by a man who threw a Molotov cocktail through a window, Nassau police say.

The fire broke out at a home on Harrison Avenue at around 6 a.m.

Detectives say the oldest daughter's ex-boyfriend Joseph Ferrufino, of Baldwin, poured a flammable liquid onto the family's new Mercedes Benz parked in the driveway. He then allegedly threw a Molotov cocktail into the younger daughter's second-floor bedroom.

Police confirmed that this is the second incident at the home in the past seven days.

In video obtained exclusively by News 12 from a neighbor's surveillance camera, a person is seen running toward the home on Nov. 17. Police say Ferrufino through a Molotov cocktail at the front bay window, but it didn't break.

Police confirm that an alarm was installed as part of the investigation, which sends an instant message to 911. They would not say whether it captured Ferrufino setting the fire.

Ferrufino is facing two arson charges in connection with today's incident. It doesn't appear that he's been charged with anything related to last week's event.

He's expected to be arraigned Wednesday.
