Amir Khan yesterday claimed that a scorecard in his controversial defeat by Lamont Peterson in Washington last month was "interfered with" by a mysterious figure at ringside.
Khan used several Twitter messages to allege that the World Boxing Association supervisor Michael Walsh was being disturbed and interrupted round after round by a man sitting to his left and that the scoring for the fight -- which Khan lost narrowly on points -- was "dodgy".
In a string of almost 30 tweets, Khan also posted pictures of the unidentified figure sitting near Walsh, where he can clearly be seen picking up the yellow score ticket and interrupting Walsh, which is against fight rules.
"Who is this guy?" Khan asked on the social networking site. "What was he doing? Will be interesting to see if we get our answer. I knew there was something dodgy with the scoring."
The IBF is holding a hearing into the fight on January 18 but insisted that "the master scorecard was not tampered with in any way".
