A man alleged to have spat on and punched two passengers at Euston station before fleeing is being sought by police.
After leaving a train which arrived from Manchester Piccadilly, a man attacked two people who had just stepped off the same train.
He first spat at them before punching both, leaving one – another man – with serious head injuries requiring hospital treatment.
The suspect then ran to the Underground and boarded a Northern Line train from platform three, heading north.
The attack, which is being treated as attempted GBH by police, took place on December 10 at 11pm.
