MARYLAND HEIGHTS, Mo. (KSDK) – A one-time assistant principal for the Parkway School District has resigned after allegedly exposing himself to an undercover Maryland Heights police officer in a parking lot earlier this month, officials confirm to Five On Your Side.

Terry Martinez, 49, had been an assistant principal at Parkway West High School for nearly four years. He was in the process of transitioning to a new position as the district's fine arts coordinator when he was arrested.

Police say he exposed himself to a male undercover officer in the parking lot of Creve Coeur Park in broad daylight.In all, police say they arrested 15 people in a sting that took place over several days.

A spokesperson for Parkway says once police notified the district of Martinez's arrest, the school put him on administrative leave and told him they would pursue his termination or he could resign. He resigned on June 10.

The Board of Education accepted the resignation during a closed session the next day, the Parkway spokesperson confirmed to NewsChannel 5 in an email.

The district says Martinez passed an FBI background check when he was hired in 2010.

Before serving as assistant principal at Parkway West, he was a band director at O'Fallon Township and St. Charles West High Schools, according to a prior news release from the district.
