NIAGARA FALLS – A 27-year-old Niagara Falls man was arrested Friday night, capping a months-long investigation into powder cocaine sales in the city.

Niagara Falls police narcotics detectives stopped Antoine R. Bones, of Center Avenue in his car on Highland Avenue, about two blocks from his home, at about 6 p.m.

Capt. David LeGault, head of the narcotics unit, said that under a Niagara Falls City Court search warrant, detectives then seized about 11 ounces of suspected powder cocaine from Bones’ home.

Bones is being held on a charge of first-degree criminal possession of a controlled substance and will be arraigned next week in Niagara County Court, LeGault said.
