A Sterling, Virginia, woman has been charged with felony assault after she poured a window cleaning agent into the coffee maker at her job over several weeks, the Loudoun County Sheriff's Office said.

Mayda Rivera-Juarez, 32, was arrested Friday after several of her former coworkers reported the incident.

According to the Loudoun County Sheriff's Office, several of Rivera-Juarez's coworkers became ill after drinking the tainted coffee.

The sheriff's office did not name the business where Rivera-Juarez's worked, but said it is located in the 45000 block of Ocean Court in Sterling.

Rivera-Juarez is being held without bond at the Loudoun County Adult Detention Center.
