Four people, including a police officer, have been injured in an attack by a wild boar in a residential area of Berlin.

Authorities said the 120kg animal was shot dead.

Police said the boar bit a 74-year-old man on the back and leg, and knocked a 74-year-old woman to the ground and injured her hip in the Charlottenburg area of the German capital.

It also bit a 24-year-old woman before she climbed on to a parked car to escape it. All three were treated in a hospital.

A police officer who arrived on the scene was also attacked, suffering a cut leg, before he pulled out his gun and killed the animal with "multiple shots".

Wild boars are relatively common in suburban Berlin, but rarely cause problems beyond digging up gardens.
