A man was knocked unconscious on a train to the city during a scuffle now being investigated by police.

The row erupted onboard a train from Blackfriars, in London, to Brighton at around 2.40pm on Saturday, June 24.

The man was travelling with his friends on a Thameslink train to the coast, when another man boarded the train and sat next to him before becoming verbally aggressive with the passenger.

He then punched the passenger in the head, knocking him unconscious and giving him a number of bruises and a perforated ear drum.
