BOLTON boxer Amir Khan's Twitter account appears to have been hacked. 

More than 20 tweets were posted on Thursday morning on his social media account, which has 1.67 million followers.

The spam links covered a range of topics - from sleeping positions for couples to 'Kim Kardashian's Transformation' and other more sexually explicit ones.  

The account's original handle was also changed to @AmirKingKha1. 

Twitter users were quick to notice and comment on the boxer's social media misfortune. 

In July 2014, the Olympic silver medalist's account was hacked when pictures of two naked girls were posted.

Another account with the original handle @amirkingkhan has since been set up. 

Its first tweet reads: "Apologies for spamming your timeline. My Twitter and Facebook got hacked!! Thanks to the Twitter & Facebook team for helping me recover it:)"
