SEAFORD - Nassau County police say they arrested a BOCES teacher's aide today, after a co-worker allegedly caught the woman showing a sexually explicit video to a 13-year-old boy.

Officials say Tanya Thompson, 29, of Rockville Centre, used her cell phone to show the inappropriate video to the student today at the BOCES school in Seaford.

Police say Thompson is charged with endangering the welfare of a child. She's due to appear in court on April 13.
