At the time, Westergaard said he wanted his cartoon to say that some people exploited the prophet to legitimize terrorism. However, many in the Muslim world interpreted the drawing as depicting their prophet as a terrorist.
Over the years, Danish authorities have arrested other suspects who allegedly plotted against Westergaard's life.
After three such arrests in February 2008, Westergaard issued a statement, saying, "Of course I fear for my life after the Danish Security and Intelligence Service informed me of the concrete plans of certain people to kill me. However, I have turned fear into anger and indignation. It has made me angry that a perfectly normal everyday activity which I used to do by the thousand was abused to set off such madness."
Scharf said authorities have taken measures to ensure Westergaard's safety, and that the protection has "proven effective."
