A Massachusetts man who works in pediatric health has been charged with possession of child pornography.
The Middlesex County District Attorney's Office said Peter Sahagian, 61, of Arlington, was arrested Wednesday. Sahagian, a nurse at the pediatric unit of Cambridge Hospital, is accused of having a flash drive with multiple pornographic images of children.
Arlington Police and an FBI representative visited Sahagian's home last Thursday after a tip from the National Center for Missing and Exploited Children.
The DA's office said Sahagian is believed to have downloaded the images using his computer. None of the images are believed to be of his patients.
"We treat all matters of patient and staff safety very seriously," Cambridge Health Alliance said in a statement. "We are fully cooperating with local law enforcement authorities, who have informed us there is no indication the alleged criminal activity was work-related or involved any patients from the practice."
The alliance added that it had launched its own review.
Sahagian was arraigned Wednesday and released on personal recognizance. He is required to stay away from children under 18 and he is not permitted to use the internet.
Sahagian is due back in court July 24.
