A deputy mayor of Finland’s capital is facing possible legal action, and calls for him to pay compensation for damages and to resign, after he was caught red-handed spray-painting graffiti in a railway tunnel last weekend.

The Finnish Transport Infrastructure Agency told public broadcaster YLE on Wednesday that cleaning up graffiti illegally painted by Paavo Arhinmäki, one of the four deputy mayors of Helsinki, cost the city around 3,500 euros ($3,830).
