US restaurant chain Buffalo Wild Wings says its Twitter account was hacked and crude comments were briefly posted, but later deleted.
A spokeswoman for the Minneapolis-based company says Buffalo Wild Wings is in touch with Twitter and "will pursue the appropriate action against the individuals involved".
The company apologised on its Twitter account, saying the posts "obviously did not come from us".
Known for its sports bar fare such as chicken wings, Buffalo Wild Wings was purchased in a deal finalised earlier this year by Roark Capital Group, which owns Arby's restaurant chain.
