LUMPUR - The Asian Football Confederation has imposed lifetime bans for match-fixing on four players and an official in Nepal and a Tajik referee. "These cases show that the AFC's strategy against match-fixing is delivering concrete results," the regional body said, adding that it has "a zero tolerance to match-manipulation". Nepali official Anjan K.C. and the four players -- Bikash Singh Chhetri, Sandip Rai, Ritesh Thapa and Sagar Thapa -- were found guilty of offences relating to various friendly internationals during the period 2008-2012. Tajik referee Murtazoev Parviz was found guilty of conspiring to influence the result of an October 6, 2015 match between the Maldives and Tajikistan in the AFC U-19 Championship. Parviz was the game's appointed referee liaison officer.
