A Kitchener medical marijuana dispensary is once again involved in a police investigation.

After being ordered to cease and desist last month, the Green Tree Medical Dispensaryre-opened over the weekend under new ownership.

Neighbours say there's been a steady stream of customers to the store over the last few months, but people looking for marijuana at the site Tuesday came away empty-handed.

Area residents say Waterloo Regional Police cruisers were at the site in the morning, and all signs point to it being closed.

In a statement police say they are investigating the new dispensary.

They are reminding businesses that the laws haven't changed and what thecompany isdoing is illegal.

On March 10,$30,000 worth of marijuana and hash was seized from the Green Tree Medical Dispensary.

Four people were arrested during that raid.

Now there is a sign inside saying there are new owners and the business is now called Herbal Leaf.

As of Tuesday night there is no indication whether the shop is permanently open or closed.

The owners could not be reached for comment.
