A licensed pharmacist in Niagara Falls is facing charges after police say he compelled a woman to remove her clothes before he would fill her prescription.

Niagara Falls Police and the DEA arrested 81-year-old Robert Kenzia for coercion Tuesday morning.

Police say Kenzia, a licensed pharmacist at McLeod's Pharmacy on Buffalo Avenue, threatened the customer to notify other pharmacies to not fill her prescriptions if she did not comply with his demands.

The Drug Enforcement Administration is now conducting a full audit of the pharmacy to see if other illegal activity has occurred at this location.

Longtime friends of Kenzia are in disbelief.

"When I saw it, I laughed. It's not him," said Diane Curtis a friend of Kenzia. "I'm shocked...truly shocked."

Niagara Falls Police say it is suspected that there may be other victims who have yet to come forward.

Anyone with information is asked to call the tipline at 286-4591.
