A Westchester County judge set $100,000 cash bail Wednesday for a Great Neck plastic surgeon facing multiple weapons charges.

Matthew Bonanno, 47, appeared at the Westchester County Courthouse. He also appeared at Tuckahoe Village Court Tuesday after being arrested last week outside of a Tuckahoe bar.

Police say a bystander allegedly overheard him threatening to kill his ex-wife and her family. They say when they checked Bonanno's car parked outside his ex-wife's home in Tuckahoe, they found an arsenal of weapons.

Officials say officers found more weapons during their searches of Bonanno's homes in Mount Pleasant and in Great Neck.

Bonanno's ex-wife was in the courtroom but had no comment. Her family members also did not comment.

Bonanno's lawyer was not happy by the bail set by the judge. "A $100,000 cash or $500,000 bond is tantamount to no bail. It just goes from remand to the equivalent of remand. It is completely extraordinarily high bail for weapons charges,” said attorney Paul Gentile.

The judge ordered Bonanno to surrender his passport and wear an electronic monitoring device if he makes bail.

His case is expected to be heard by a grand jury on Friday.
