A doctor at Vienna’s Hanusch Hospital was attacked on Wednesday after a patient allegedly poured butyric acid over him, prompting the temporary closure of several outpatient clinics due to strong fumes.
According to police, the woman reportedly lost control during a consultation and splashed the corrosive substance on the doctor, with four other people also coming into contact with the acid. Officers arrived quickly and arrested the suspect. Investigators have yet to determine the motive, and a hazardous-materials specialist was called in to confirm the substance used.
The hospital’s lung medicine, rheumatology and dermatology outpatient departments will remain closed until at least Thursday, the Austrian Health Insurance Fund (ÖGK) said. A specialised cleaning team has been deployed to remove the persistent stench caused by the acid.
“Thanks to the swift intervention of our security staff, further harm was prevented,” the ÖGK said in a statement, adding that the safety of staff and patients was the hospital’s top priority.
Police believe the suspect purchased the butyric acid online. She is being investigated on suspicion of intentional grievous bodily harm.
Butyric acid is known for its powerful, unpleasant odour and can cause severe irritation. Inhaling its fumes may lead to coughing, nausea, vomiting and potential lung damage, while skin or eye contact can result in serious chemical burns.
