A senior Taoyuan police official was caught with drugs after unknowingly arranging a party meetup with an undercover officer, an embarrassing blow to the force's image.

• A 41-year-old police officer in Taoyuan used a dating app to invite people to parties, offering "party favors."
• The person he arranged to meet turned out to be an officer on internet patrol duty, who identified himself and searched him on the spot.
• He was found with meth and a large amount of GHB, the sedative known as liquid ecstasy or a date-rape drug.
• He was sent to prosecutors on drug possession and attempted supply charges, released on bail, and is being fired with two major demerits.

Outlook: Police are tracing where he got the drugs and checking whether other officers were involved, though none have been found so far.
