The two-storey High Street-based station, in Tettenhall, Wolverhampton, closed down several years ago and was sold off at auction in September 2019.
Now Conservative council candidate Ellis Turrell has said more can be done to close down and protect the site, which is attracting criminal activity.
Mr Turrell said: “The condition of the former police station site on Tettenhall High Street is appalling.
"The back wall has been demolished, which has allowed people to trespass on the site and attempt to break into the building. It is only a matter of time before somebody gets hurt.
“The police station should never have been closed, and I know many residents were concerned to see the building vacated by the police. But it is imperative that the local authorities take action now to secure the site and prevent further damage.”
Mr Turrell, the candidate for Tettenhall Wightwick, said the back wall of the site had been knocked down and its windows have been smashed in – and he has seen evidence of people accessing a small outbuilding at the back of the site.
Councillor Jonathan Crofts, who represents Tettenhall Wightwick, said: “I have raised this directly with Wolverhampton Council and the local policing team, as the site clearly needs to be closed off to prevent access.
"There is evidence of people gaining access to the small outbuilding at the back of the site, and also some damaged glass where it looks like somebody has attempted to break in to the building.
“I will continue to work with the council and the police to get this resolved.”
