A self-confessed 'stupid' phone snatcher got a dose of instant karma after a dramatic police chase led to his arrest.

The thief, Bradley McMillan, was one of two spotted by officers travelling at around 60mph on high-speed e-bikes on a busy road in central London.

Armed response cops were called out after receiving reports of phones being snatched - with suggestions the thief may have been carrying a weapon.

Taking off after McMillan, officers equipped with Tasers followed him up Exhibition Road in Kensington - a thoroughfare often packed with tourists visiting the Science Museum and the Natural History Museum.

'We have two Sur-Rons failing to stop as part of a declared firearms incident,' the officer radios in, seen in dramatic body-worn footage issued by the Met Police.
