Officers have shut down a house left in "major disrepair" that was being used to sell drugs.
The house, on residential street Crofton Road, Rock Ferry, had been abandoned by its owners, police said.
A man "with no authorisation from the landlord" was occupying the home, despite it being in a state.
After receiving intelligence from members of the public, officers attended the home on August 17 to take possession of it.
The multi-agency approach came after it was reported the home was being used to sell drugs.
Anti-social behaviour was also reported at the scene.
