Police seized more than half a million dollars in weed and thousands more in grow-op equipment from a home in Winnipeg this week.

Members of the Winnipeg Police Service tactical unit entered a home in the 100 block of Deering Close on Wednesday with a search warrant.

Investigators discovered 488 marijuana plants in the home worth an estimated $546,560 on the street, police said. About $13,600 in growing equipment was also seized.

Police arrested a 57-year-old man for his alleged involvement. He is facing charges for production of an illegal substance and possession of an illegal substance for the purpose of trafficking.

He has been released on a promise to appear in court, police said.
