RCMP are saying very little about why officers went to the offices of Canadadrugs.com, a Winnipeg-based internet pharmacy.

Police confirmed that they did go to the office building on Terracon Place, in the city's Transcona area, on Wednesday morning. However, they would not say why, citing officer safety.

People at a nearby business told CBC News that several RCMP officers and vehicles were seen there for some time, starting in the morning.

Employees leaving the office building on Wednesday afternoon either declined comment or said they were not aware of the police presence.

The internet pharmacy has been the focus of investigations in the past.

Last year, Health Canada suspended Canadadrugs.com's establishment licence, meaning the company could not sell prescription drugs to pharmacies until the federal department's concerns were addressed.

As well, the company was ordered in 2012 to stop marketing drugs online into the United States through thousands of websites that were registered in different countries.

Canadadrugs.com was also named in a U.S. government investigation into counterfeit cancer drugs.
