A member of the public who bravely approached a man and rebuked him for being 'rowdy and aggressive' ended up being slashed with a knife in Sheffield.
Police said the attacker first threw a punch after being confronted last night on Fairthorn Road in Firth Park, before drawing a knife and leaving the victim with a cut to the chin.
The attack took place at around 8.30pm and police said the injury was not serious but required treatment.
