Presumably with a twelve-boar shotgun

From The Metro:

Switzerland: An injured boar attacked his father and his two sons as they played in their garden. The 90kg (200lb) animal bit Markus Lainer in the leg before fleeing. The 37-year old said: "I tried to fight it off, hitting it until it let go. It ran off and I noticed it didn't have its back feet."

Police in the northern village of Adlikon later shot the boar and said it had been injured in a collision with a train.

Makes a change from "the prisoner fell down the stairs", I suppose.
