The head of Spain was slugged in the face by a devious teenager during a campaign event Wednesday.

Prime Minister Mariano Rajoy was speaking to supporters at a rally in the Galicia region when the assailant sucker-punched him in the head.

The 60-year-old Rajoy was not hurt in the attack, but continued the event with a red welt on his face.

The teen was arrested, though his motive remains unclear.
