The police don't wear uniforms or identify themselves. If you hit him, it's not assaulting a police officer.

If it exceeds 24 hours, you must be released unless a detention decision is made to detain you. The longest administrative detention 15 days, the longest criminal detention 37 days. However, your illness is not serious and you will not be detained.
