CANBERRA, Australia (AP) — An Australian senator has had a raw egg cracked over his head and faces censure from his fellow lawmakers after sparking outrage by blaming Muslim immigration for the New Zealand mosque shootings.

Sen. Fraser Anning came under blistering criticism over tweets on Friday including one that said: "Does anyone still dispute the link between Muslim immigration and violence?"

Television cameras caught a 17-year-old boy breaking an egg on Anning's head and briefly scuffling with the independent senator while he was holding a news conference Saturday in Melbourne.

Police said the boy was arrested but was released without charge pending a further investigation.

The government and opposition party agreed to pass a censure motion against Anning over his stance on the Christchurch shootings when Parliament resumes in April.
