Vilks was largely unknown outside Sweden before his Muhammad drawing. At home, he was best known for building a sculpture made of driftwood in a nature reserve in southern Sweden without permission, triggering a lengthy legal battle. He was fined, but the seaside sculpture — a jumble of wood nailed together in chaotic fashion — draws tens of thousands of visitors a year.
Vilks' life changed radically 13 years ago after he drew a sketch of Muhammad with a dog's body. Dogs are considered unclean by conservative Muslims, and Islamic law generally opposes any depiction of the prophet, even favourable, for fear it could lead to idolatry.
Al-Qaeda put a bounty on Vilks' head. In 2010, two men tried to burn down his house in southern Sweden. Last year, a woman from Pennsylvania pleaded guilty in a plot to try to kill him.
