A Nassau County detective accused of being a slumlord pleaded not guilty to charges he violated Suffolk town codes Thursday.

Town of Brookhaven officials say 36-year-old Paul Fuina has three illegal apartments in a Mastic Beach home he owns. Neighbors say Fuina made his tenants sign forms promising not to allow any town or county officials in the apartments. They also say he wore his gun and badge while collecting rent.

A spokesperson for Fuina says the Nesconset resident is being targeted because he is a cop and claims he doesn't own the home in Mastic Beach. However, the town says it has the documents to prove Fuina is the homeowner.

Fuina is due back in court April 3.
