(BALTIMORE) -- A Saturday morning of shopping turned into an emergency hazmat situation at a Baltimore Walmart where two patrons threw bleach and disinfectant at one another, officials said.
Baltimore County Police responded to a call at about 10:48 a.m. Saturday and found two women fighting -- supposedly over a guy -- inside the store.
The bleach and disinfectant created toxic fumes, forcing the immediate evacuation of the entire Arbutus store, officials told ABC News affiliate ABC 2. It closed for several hours.
Fire, EMS and hazardous materials units were dispatched to the scene, as well as 10 medics.
Nineteen people reportedly received treatment, including three Walmart employees. One person was taken to the Wilmer Eye Institute at Johns Hopkins Hospital for treatment, officials said.
Three Walmart employees were being treated for respiratory problems, a Walmart spokeswoman told ABC News.
According to Baltimore County police, 33-year-old Theresa Monique Jefferson chased a woman into the Walmart, knocked her to the ground and began pouring bleach and ammonia on her. Most likely unknown to the attacker, the combination of the two common household chemicals forms a toxic gas.
Jefferson was arrested and charged with first-and second-degree assault, theft under $100 and malicious destruction of property. She is being held at the Baltimore County Detention Center on $350,000 bail.
