A Twitter user mistakenly charged with stirring up race-hate has vowed to sue Scotland Yard over the blunder.

Matthew Doyle, 46, triggered a storm online after writing that he had confronted a Muslim woman on the streets of Croydon about the Brussels terror attacks and she had given him a ‘mealy-mouthed’ response.

He was arrested over his comments on Wednesday by Croydon Police Community Safety Unit, taken into custody, charged with posting material ‘likely to stir up racial hatred’ and was due to appear in court yesterday morning.

But then police were forced into an embarrassing U-turn by the Crown Prosecution Service on Friday night, charges were dropped and PR executive Mr Doyle was released.

The Met was told it did not have the power to make the controversial charging decision and had failed to consult the Attorney-General, the Government’s top law officer, or the CPS.

Last night LSE graduate Mr Doyle told The Mail on Sunday he planned to take legal action over his ordeal.

‘I cannot understand why I was detained, my flat trashed, my passport seized and two PCs, two tablets and my phone taken,’ he said.

‘I was denied a shave, shower, food. I was stripped of any dignity to appear in court without looking like a dishevelled hobo that I am not.’

He accused ‘nameless Twitter trolls’ of ‘fanning the flames’ and making death threats against him, and went on: ‘For the Met to bow to social media rows - it is not only foolish of them but I will be making a complaint against them and damages for trashing my flat, taking all my electronic stuff from my flat and forcing me to leave London.’

The tweet, posted from the Twitter account @matthewdoyle31, sparked social media outrage and countless parodies

Scotland Yard said: ‘Matthew Doyle, 46, of South Croydon was charged by police on Friday, 25 March, with an offence under Section 19 of the Public Order Act 1986.

‘Following discussion with the Crown Prosecution Service, Mr Doyle is no longer charged with the offence and will not be appearing at court.

‘Police may not make charging decisions on offences under Section 19 of the Public Order Act.’
