HAUPPAUGE, N.Y. — A Florida man has been extradited to New York to face charges that he photographed himself engaging in sex acts with three children he was baby-sitting.

Newsday reports that 27-year-old Benjamin Fielman pleaded not guilty Friday to a 27-count indictment.

Prosecutors in Suffolk County on Long Island say Fielman abused the three children between 2009 and 2014 when he was living in Commack, New York.

District Attorney Timothy Sini did not release details including the children’s genders.

Sini said authorities believe there may be more victims.

Fielman is serving a 10-year sentence in Florida after pleading guilty to felony sex crimes involving children in June 2017.

Fielman’s attorney, Bryan Browns of the Suffolk County Legal Aid Society, said he has seen “no evidence against him” in the New York case.
