New Zealand Olympic runner Zane Robertson has been arrested in Kenya for alleged sexual assault and possession of an unlicensed AK-47 assault rifle. He is currently under custody for five days while investigations are ongoing. Robertson, who is already serving an eight-year ban for doping, was arrested at his home in Iten, a renowned training base for long-distance runners. The allegations arose from a party at his house, where a woman claimed to have been assaulted. Police found the rifle and ammunition after being initially denied access to the property. Robertson won a bronze medal in the 2014 Commonwealth Games.
