<br/>New Zealand anti-whaling activist Peter Bethune has been deported from Japan after receiving a suspended two-year sentence for obstructing Japanese whaling in the Antarctic Ocean.<br/><br/>Reports say Bethune, 45, was sent home on an Air New Zealand flight left Tokyo's Narita airport for Auckland. Bethune was convicted at Tokyo District Court on Wednesday on a number of charges including injuring a whaler by hurling a rancid butter stink bomb during the latest campaign by the US-based Sea Shepherd Conservation Society. His sentence was suspended for five years because, the judge said, Bethune had no criminal record in Japan, had apologised and paid for damage he caused, and because he had said he would join no more Antarctic missions.
