State Police at Niagara have charged a 25-year-old Niagara Falls man with first-degree rape, after receiving a complaint from a female acquaintance of his that she had been sexually assaulted.

Troopers arrested Robert W. MacKenzie, of Bellreng Drive, Niagara Falls, on Monday.

After his arraignment before Town of Lewiston Judge Thomas J. Sheeran, MacKenzie was sent to the Niagara County Jail on $10,000 cash bail.
