Australian counter-terrorism police have arrested a man accusing him of seeking to help the Islamic State terror group by developing missile technology. Police Commissioner Andrew Colvin said, the man researched and designed a laser warning device that could alert the Islamic State group to incoming guided weapons used by coalition forces in Syria and Iraq. <br/><br/>The man is also accused of researching, designing and modeling systems to assist the extremist group's efforts to develop their own long-range guided missiles. He was arrested during a raid at his home in the rural New South Wales town of Young following an 18-month investigation.<br/><br/>
