LI Man Arrested With Large Weapons Cache: Police
Police said the investigation into the man began because of a report of threats against his estranged wife.

TUCKAHOE, NY — A 47-year-old Long Island man was arrested Monday on multiple criminal possession of weapons charges. The Tuckahoe Police Department said the arrest was the result of an investigation into a report that Matthew J. Bonanno, of Great Neck, Nassau County, had made threats against his estranged wife, who is a Tuckahoe resident, and her family.
Police said they were contacted by someone who heard the threats and believed Bonanno, a plastic surgeon, was armed.
Tuckahoe police went to Growler's Beer Bistro in Tuckahoe, where Bonanno was at the time, and found him to be illegally in possession of a loaded Glock semi-automatic handgun.
