Former Asian football administrator Peter Velappan says Mohamed bin Hammam should not escape punishment for alleged corruption despite resigning from all football-related positions and accepting a new life ban from FIFA.

Bin Hammam, a FIFA executive committee member from Qatar who challenged incumbent Sepp Blatter for the presidency last year, gave up his long-running dispute with football's world governing body organization after being found guilty by FIFA of "repeated violations" of its code of ethics while head of the Asian Football Confederation.

Velappan, who was AFC general secretary from 1978 to 2007, said Tuesday the AFC and world governing body FIFA should pursue investigations into alleged corruption and misappropriation of funds by former bin Hammam.
