A pharmacist at MacLeod's Drugs in Niagara Falls was arrested Tuesday morning after he was accused of coercing a female customer to take off her clothes in front of him before he would fill her prescription, authorities announced.

The pharmacist, Robert W. Kenzia, 81, also is accused of threatening to tell other drug stores not to fill her prescriptions unless she complied with his demands, authorities said.

Niagara Falls police investigated the allegations at the Buffalo Avenue pharmacy with the Drug Enforcement Agency, which is conducting a "full audit" of MacLeod's to determine if there has been any other illegal activity at the business.

Investigators believe there may be more victims. They asked anyone with more information to contact the police department's Narcotics Intelligence Division tip line at 286-4591.
