A Riverhead teacher is accused of possessing child pornography.

James Finch, 48, was arrested Thursday at his Riverhead apartment. He is a teacher at Riverhead High School. Police say they seized two computers, CDs and DVDs containing child porn.

?He confirmed to detectives that the images on the computer were his and they're images of young children in sexual performance,? says Suffolk Deputy Inspector Robert Oswald.

Cops say Finch's arrest was the result of an ongoing undercover investigation into child pornography in Suffolk County. Police tell us they don't believe Finch abused any students at Riverhead High School.

School officials say Finch has been suspended without pay. He pleaded not guilty to a charge of possessing a sexual performance of a child.

Finch is also a retired U.S. Navy officer. Police say he is separated from his wife and has two children. Finch faces up to four years in prison if convicted. He is due in court on May 6.
