A lawyer for a paraplegic murderer is suing the NYPD for records of how the department treats disabled prisoners after the city went back on a $45,000 settlement of a suit claiming cops locked the killer in a cell without his wheelchair.

Amy Jane Agnew, attorney for Wayne Stewart, 38, sued the NYPD last week, seeking all complaints made by wheelchair-bound suspects against the police. Agnew says she believes cops routinely violate disabled prisoners’ civil rights.

Stewart, who is now serving 33 years to life for murder, claimed in his Manhattan federal suit that he got sepsis after cops laid him face-down on the floor of a cell at the 25th Precinct station house in July 2014.

A city Law Department spokesman said the settlement was withdrawn because Stewart refused to drop a second personal-injury suit over the same incident.
