A man has been charged for allegedly assaulting a hotel employee with a ninja-like sword in Waikiki.

Brian W. Schacher has been charged with first-degree assault and second degree assault. His preliminary hearing at District Court is set for Thursday. He is being held in lieu of $500,000 bail.

Shortly after 12 p.m. Saturday, police said a woman at the Ewa Hotel located at 2355 Cartwright Road reported a male was swinging a two-foot “ninja sword” in the lobby area and arguing with front desk employees, according to a court document.

Clad in a white robe, blue top and black backpack, Schacher swung the sword toward them, striking a female employee three times. Police said she suffered injuries to the lower part of her body.

A witness fled to a room with five other people.

Police located Schacher on the fifth floor of the hotel and arrested him.
