A racist and abusive comment was accidentally posted on British Ariways' official Twitter page, highlighting the risks involved in using the social networking site, Travelmole reports.The foul-mouthed tweet, originally from another user of the site, was re-tweeted by BA to its 210,383 followers before communications chiefs spotted the error. According to Mirror News a post appeared on the timeline of the BA-verified account in which an angry customer was called a "g**k" and told to "f*** off back to your own country" by another user.The abusive comment was made by a user called 'Asian Ronaldo' who was responding to a tweet from a user called 'JaeLadd' complaining about his flight being cancelled. The offensive remark was then re-tweeted by @British_Airways to its followers.BA said: "We apologise for any offence caused and we are investigating how this has happened."A spokesperson for the airline said it wasn't clear if it was the result of the airline using an auto-retweet function or if BA's account had been hacked. BA staff attempted to distract attention by reposting a video of their latest ad campaign.The tweet has since been removed and seemingly, so has Asian Ronaldo's Twitter profile.
