A Massachusetts teacher who authorities say had videos of young girls being sexually abused on his computer has pleaded guilty to child pornography charges.
Authorities say 27-year-old Warren Anderson entered his plea in federal court on Tuesday.
Anderson, of Lowell and Harvard, was a math teacher at the Narragansett Regional School District based in Templeton.
Anderson was placed on leave after his arrest last year.
Federal prosecutors said in a statement that Anderson was interviewed in August 2018 as part of an ongoing investigation into the online trade of child pornography through the Kik messenger app.
Prosecutors say thousands of child pornography files were found on Anderson's computer and he admitted to accessing sites on the dark web to obtain the files.
He is scheduled to be sentenced Oct. 16.
