A former Twitter employee who shut down Donald Trump's account last month, says he did so by accident - but that some of the US president's tweets do breach Twitter's rules 

Bahtiyar Duysak claims he wasn't paying attention when a complaint came in about an account an hour before the end of his last day at the San Francisco-based company. 

"I just treated it as an ordinary account. I should have double-checked things which I didn't do due to the hectic and tiredness of my last day. Obviously I clicked a few wrong things which I shouldn't have done, and this has led to this result."

Those "wrong clicks" caused a media sensation.

Twitter quickly blamed a customer support employee on his last day at work and said it has taken steps to prevent such an incident happening again.

Trump - who has 44 million Twitter followers - blamed a "rogue employee".

It may have been a mistake, but Duysak believes some of the president's recent tweets are a breach of Twitter's rules. 

"His re-tweets of, for example, right-wing groups in England or videos of violence in some Dutch villages are definitely spreading hatred."

Twitter said it had nothing more to say and the White House did not respond to a request for comment.

Following the incident, Duysak headed home to Germany.

He says he is now fighting attempts by some US news organisations to cast him in a negative light.

And he says he has apologised to, and made peace with, Twitter.
