Doorbell prankster that tormented residents of German apartments turns out to be a slug

People suspected teenagers playing ding dong ditch and called police, who found animal crawling on the door panel

Inhabitants of an apartment block in Bavaria, southern Germany, who called police to investigate the relentless buzzing of their doorbells late at night were surprised to find the culprit was not a teenage prankster as they had suspected, but a slug.

The slug had been sliding up and down the bell plate, creating havoc in the building and tearing angry residents out of their beds long after midnight when they could not sleep for the noise.
