A 64-year-old grandfather working at two homes for the mentally disabled repeatedly raped one female resident and molested several others who had been in his care, Suffolk officials charged Wednesday.

The 20-count indictment unsealed in a Suffolk court Wednesday against Pervez Mahmud of Manorville detailed a string of sexual assaults at two residences where he worked as an aide.

Assistant District Attorney Elizabeth Miller said in court that Mahmud had sex several times with one victim. In another alleged attack, Mahmud molested an elderly woman. All of the unidentified victims were between the ages of 45 and 71.

Mahmud pleaded not guilty yesterday to charges of second-degree rape and second-degree criminal sexual act. His attorney, Christian Killoran of Miller Place, said in court the case against Mahmud is weak and deficient. He declined to comment outside court. Mahmud is married with three children and two grandchildren.

Before the arraignment, Suffolk District Attorney Thomas Spota said Mahmud had sexual contact with a resident at an AHRC of Suffolk home in Bay Shore on Nov. 3 while he was filling in for a co-worker. Officials said the company suspended Mahmud six days after the alleged attack.

An investigation by Southold police and the district attorney's office later found Mahmud also assaulted five women between June and November at an AHRC group home in Southold where Mahmud was normally assigned to work, Spota said. Mahmud had worked at the company for a year and a half, officials said.
