Shingles’ cousin Tyriek Fortune was arrested on a previous charge.
Lawyer Wale Mosaku said his client came forward after The News exclusively reported in July that Grieco and six other cops from the 75th Precinct in East New York are under investigation by the Internal Affairs Bureau for a host of allegations — including illegal searches of apartments and stealing jewelry and cash — dating to July 2011.
A source told The News on Tuesday that Grieco and several other cops have been questioned by the IAB and that the investigation is ongoing.
Grieco has also been named in at least 12 lawsuits in federal and state courts alleging civil rights violations, including two filed this month. The city has paid at least $114,000 to settle three of the cases, according to court records.
The NYPD has refused to comment on the lawsuit.
