Man who took his pint of beer while fleeing the London terror attacks has gone viral

An image of a man who resolutely kept hold of his pint of beer while fleeing the scene of the weekend's terror attack in London has gone viral.

Video shows the man appearing calm and focused on not spilling a drop as others ran past him to escape the area.

The man has become an unlikely hero from the attack, hailed as the embodiment of British humour and defiance.

The attack saw seven people killed and 48 injured, including Christchurch man Oliver Dowling

A van mowed into pedestrians on London Bridge at 10:08pm Saturday night (local time) before three men jumped out of the van and began stabbing people.

The three suspects, who were wearing fake suicide vests, were shot dead by police at the scene.

London's Metropolitan Police arrested 12 people in the Barking district of east London in connection with the attack.
