A senior Taoyuan police officer was caught with methamphetamine after unknowingly inviting an undercover officer to a drug party — bad news for the force's reputation, and a sign internal discipline is being enforced.

• A 41-year-old police supervisor used a dating app to invite people to parties, offering "party favors."
• The person he arranged to meet was an officer on internet patrol duty, who identified himself at the meeting and found meth on him.
• The supervisor was stunned to discover his contact was a fellow officer, and outranked by him.
• He has been referred to prosecutors and fired, with two major demerits filed with the city government.

Outlook: Investigators are now tracing where he got the drugs and checking whether other officers were involved, with none found so far.
