A judge refused to lower the bond Wednesday for a Harris County Sheriff’s deputy who investigators say stole narcotics from drug dealers while on duty and sold those drugs for a profit.

Christopher Ellis, 34, was arrested while working his patrol shift Monday night. Authorities picked him up on Beltway 8 and Highway 249 after he allegedly sold cocaine, marijuana, Lorcet tablets and Soma tablets for $1,000 to an undercover officer.

Authorities say the investigation started after information was received about Ellis’ action.

“Our mission of transparency and accountability for the purpose of maintaining the public’s trust requires constant vigilance,” Harris County Chief Deputy Armando Tello said. “Of the approximately 4,500 men and women in service to the Harris County Sheriff’s Office, the overwhelming majority follow the strict standards and policies enforced by Sheriff Garcia.”

Ellis was charged with two counts of possession of a controlled substance with intent to deliver and his bond amounts totaled $120,000. His attorney requested a bond reduction, but that was denied.

Ellis has been employed at the Sheriff’s Office since March 2010. He has been placed on indefinite suspension. He could be sentenced to life in prison and be forced to pay a $10,000 fine if convicted.

Authorities said that they believe there are drug dealers who have been victimized by Ellis and encourages anyone with information to call the Internal Affairs Division of the Harris County Sheriff’s Office at 713-755-6517.
