PHILADELPHIA (AP) — Authorities say they are trying to find out who deployed a chemical mixture in a southwest Philadelphia police station waiting area, prompting an evacuation.
Police say the mixture, which appears to have been a combination of mace and some other substance, was deployed at about 9:15 p.m. Friday in the witness waiting area at the Southwest Detective division. No witnesses or complainants were in the waiting area at the time, police said. Several employees started coughing and reported eye irritation, so a hazardous materials incident was declared and the building was evacuated. Homeland security is investigating.
