Moosa Mohammed was so keen to protest the imminent execution of two men in Bahrain last month that he climbed onto the roof of the Bahraini embassy in London to unfurl a banner.
Then, as other protestors and police watched from below, the embassy staff appeared to struggle with him.
In an unprecedented move police broke in and arrested him.
He claims the Bahrainis threatened his life, the Bahrainis say that’s ridiculous and claim they called the police fearing a terrorist attack.
Mr Mohammed has spoken to our Senior Home Affairs Correspondent Simon Israel who has been investigating what really happened.
