Quebec's health minister says he expects health care workers to act promptly if ever they see criminal activity in long-term care facilities.

Rejean Hebert reacted today to news two female caregivers were arrested and charged with assault.

The case concerns the abuse of an 87-year-old woman at a senior’s residence in St. Lambert.

The two employees were fired last summer.

The health minister says health care workers should not hesitate to call police if they suspect wrongdoing.

“They should directly go to the police, I think there is no question,” he said.

“I'm concerned about the quality of services in this nursing home. The agency designed a special advisor to look at the quality of services in this nursing home and to report in the next weeks.”

Police say they have a video that led them to charge the women with drug trafficking and administering a potentially poisonous substance

One was also charged with armed assault.

The victim has since died, though it is unclear is the cause of death is related to the attack.

Longueuil police say the investigation is ongoing and they are working with the coroner.

They say there could be more charges in the case.
