Criminal charges laid against a Sudbury pharmacist are a "grave concern," says the Ontario College of Pharmacists.

Earlier this week Herman Reich, owner of Herman's IDA Pharmacy on Regent Street, was charged with four offences, including trafficking of a controlled substance and possession of property obtained by crime.

"We take these matters extremely seriously, which is why that allegation or that charge that has been brought forward yesterday will spark us to do a further investigation into this member," said college spokesperson Lori Decou.

"So we appreciate that things like this really get to the very fabric of that trust."

Decou said the results of those investigations will be announced at a later date. A disciplinary hearing could lead to the suspension of Reich's licence, she added, and that interim conditions could be imposed until that investigation is complete.

"The college can do everything from imposing some sort of remediation to actually removing the practitioner's registration or licence, which would, in effect, no longer allow them to practice pharmacy in Ontario," Decou said.

Reich's lawyer said he is pleading not guilty to all charges.
