BRENTWOOD - A Brentwood man was arrested last night and charged with sexually abusing a teenage student in a Westchester County school where he worked as an administrative dean.

Jose Martinez, 38, is accused of having sexual contact with a 14-year-old student at the Isaac Young Middle School in New Rochelle last year.

Between March and June of last year, detectives say Martinez had taken the boy into his office numerous times after school and engaged in oral sex with him.

In September, Martinez took an assistant principal position at nearby Jefferson Elementary School.

New Rochelle police say Martinez abruptly resigned from his job earlier this month and then disappeared from the area.

Today, Martinez pleaded not guilty to charges of engaging in a criminal sexual act.

In a statement, school district officials say Martinez passed the normal state criminal fingerprinting check before he was hired.
