The Twitter account of Jack Dorsey, boss and founder of the social network, was hacked Friday and posted insulting or racist messages.

"We are aware that @jack has been hacked and we are investigating what happened," the company tweeted.

The hacked tweets featured several hashtags apparently used in other previous hacks: #chucklingsquad and #ChucklingHela.

Racist insults against blacks and tweets apologizing for Adolf Hitler began to appear shortly before 20:00 GMT. They were quickly removed.

@jack is the first address in Twitter's history.
