An "incendiary device" was thrown through an open, bedroom window of a North Amityville home not long after midnight Wednesday morning, Suffolk police said.

Four people were inside the Benburb Street home but no one was in the first-floor bedroom when someone threw what may have been a Molotov cocktail about 12:45 a.m., police said.

No fire was started and arson detectives are on the case, police said.
