WALDORF, Md. (CBSDC) - A school custodian has been charged with selling drugs on school property after classes were dismissed in Charles County.

Kiayer Kenneth Chapman of Accokeek, 23, was arrested at North Point High School in Waldorf Thursday. He was charged with possession of a controlled dangerous substance with intent to distribute, as well as possession of a controlled dangerous substance on school property, and possession of drug paraphernalia.

The discovery came after the school resource officer received information that Chapman was selling drugs to students.

Upon further investigation, officials learned the custodian was a substitute filling in during night shifts, and selling the drugs during after-school hours.

On Tuesday, Jan. 10 at around 8 p.m., a police K-9 unit scanned the suspect’s vehicle while it was parked in the school parking lot, and determined there were drugs in the car.

In the car, police discovered two sandwich size bags of marijuana – an estimated street value of $500 – a digital scale, and some cash.

He is being held on $10,000 bond.
