Switzerland. Geneva. A police officer and a policewoman rinse the face of a caucasian man with water at the Paquis police station. The man was arrested because he has refused to pay a prostitute, who sprayed his face as retaliation. The man is completely drunk. A police station or station house is a building which serves police officers and contains offices, temporary holding cells and interview/interrogation rooms. Pepper spray, also known as OC spray (from "Oleoresin Capsicum"), OC gas, and capsicum spray, is a lachrymatory agent (a chemical compound that irritates the eyes to cause tears, pain, and even temporary blindness) used in policing. Its inflammatory effects cause the eyes to close, taking away vision. 31.03.12 © 2012 Didier Ruef..
