Unidentified criminals have fired shots at the house of a police officer in Västerås, Sweden.

The incident took place at night.

According to police, the entire family, including the policeman, were sleeping at home during the incident, reported RIA Novosti news agency of Russia.

No one was injured.

“This is an unacceptable attack on the whole society,” said Swedish National Police Commissioner Dan Eliasson. “There are cowards who attempt, through relatives, to reach those who fight for the safety of others.”
