US missionary Joseph W Cooper, who was ordered to leave the country for preaching religion in violation of visa rules, left Thiruvananthapuram for Mumbai by a flight on Wednesday morning, police sources said.

Cooper, injured in an attack by suspected RSS workers at Kilimannur near Thiruvananthapuram on January 13, was discharged from the hospital on Tuesday.

The 67-year-old missionary from New Castle, USA, who is on a tourist visa, suffered a deep cut on his right palm when he and a local team of evangelists were attacked while returning from a gospel convention at a tribal colony in Koppam near Kilimannur town.

District Superintendent of Police T K Vinod Kumar, in his capacity as the Foreigners Registration Officer, had on Monday served orders on Cooper to leave the country within seven days after he was prima facie found to have violated visa rules.
