Police arrested a man for a burglary in a city he had never visited after face scanning software deployed across the UK confused him with another person of south Asian heritage.

Alvi Choudhury, 26, a software engineer, was working at the home he shares with his parents in Southampton in January when police knocked on his door, handcuffed him and held him in custody for nearly 10 hours before releasing him at 2am.

Thames Valley police had used automated facial recognition software which matched him with footage of a suspect of a £3,000 burglary 100 miles away in Milton Keynes, according to documents shared with the Guardian by Liberty Investigates.

But the CCTV footage showed a noticeably younger man with different features apart from similar curly hair, said Choudhury, who was left confused about why he had been arrested.
