A sixth person has been arrested after an exchange student was attacked.

Police say they have arrested a 44-year-old man, of no fixed address, on suspicion of assisting an offender after the incident in Canterbury.

It comes after the victim - believed to be a German boy - was airlifted to a London hospital after he was assaulted on Thursday in Whitefriars Street, between Tesco Extra and Primark.

The scene after the attack

He remains in a serious condition.
