Khan, a British boxer, claims an unidentified man ‘interfered’ with the ringside judges during his defeat to Lamont Peterson in December, accounting for a controversial points decision.
The defeat resulted in Khan losing his World Boxing Association and International Federation light-welterweight titles.
Amir Khan, from Bolton, is expected to appeal the result on the grounds of poor refereeing decisions and irregularities on the judges’ scorecards.
Pending a hearing due to take place later this month, Khan, a 2004 Olympic silver medallist, has taken to Twitter to post a number of images relating to the bout in Washington DC.
The images appear to show a man sitting alongside judges and discussing the fight with them.
Khan also wrote: “Watch the fight from 9.10 seconds of this video there is a guy wearing a grey suit with a blue shirt wearing a hat.”
He wants the fight supervisor Michael Welsh, pictured talking to the man in one image, to publicly speak about what happened.
“It’s only right and fair to do so,” the boxer added.
