These shocking CCTV images show the moment a thug launched an unprovoked attack on a man at a cashpoint after becoming enraged because he thought he was taking too long.

The alleged attacker, who has been described as Asian and in his early 30s with a 'distinctive pointed nose', lashed out in broad daylight at the ATM outside Birchfield Road post office in Aston, Birmingham.

His 34-year-old victim was left with a black eye following the assault on January 4, which took place at around 11.15am.

Police have only released details of the offence today.

Security footage shows the man, who drove away from the incident in a silver Nissan Qashqai, wearing a navy blue Nike hooded top, light blue Adidas bottoms and flip-flops.

Investigating officer PC Leigh Harrison said: 'This was a completely unprovoked attack. The victim was using the ATM for no longer than a couple of minutes but apparently that warranted being head butted.

'Anyone who reacts so irrationally, and so violently, needs catching so I'd urge anyone who believes they recognise the man to contact me.

'The man was wearing flip-flops, unusual given that it was the middle of winter, while the CCTV seems to show him having a prominent, angular nose.'
