They're wanted for breaching public decency laws.
Police in Poland are looking for four tourists who were spotted wearing lime green mankinis in Krakow.
The group were caught on CCTV last Friday as they walked around Renaissance Market Square before hopping into a horse-drawn carriage.
The Metro reports that it hasn't been confirmed that the men are British but they spoke English and one sported a tattoo that looks like the England flag.
They caused public outrage in the historic city and were reported to police for breaching public decency laws.
The men could face up to 30 days in prison or a fine of around €1,150 if convicted.
Mankinis were made famous by the 2006 movie Borat and are popular with stag parties.
