An electrical cable pulled from the stairwell outlet through the mailbox to the apartment led to the revelation of a cannabis plant in a housing company in Leppävaara, Espoo. Police in Western Uusimaa report the discovery made on Twitter the night between Saturday and Sunday.

The police used a remote crawler in the task, says General Manager Ilkka Kantola to BTI. According to Kantola, the man in the apartment had threatened to patrol with a baseball bat in his hand.

Kantola did not yet know how many cannabis plants had been found in the apartment.
