Waterloo Regional Police went into a Kitchener home looking for drugs, and ended up unearthing much more.

Thursday, police executed a search warrant at a home on Belton Drive, near Victoria Street and Westmount Road.

Inside the building, they found and seized undisclosed amount of heroin, methamphetamine, marijuana and cash.

In addition, police allegedly discovered a number of stolen driver’s licences, passports, social insurance cards and credit cards, as well as equipment that could be used for manufacturing fake ID documents.

Three men and one woman inside the residence were placed under arrest.

Charges are pending in the case.
