Police have made a seventh arrest following an attack on an exchange student in Canterbury.

Officers arrested a 17-year-old boy from Canterbury yesterday evening and he remains in custody.

It comes after a German student was airlifted to a London hospital after he was assaulted on Thursday in Whitefriars Street, between Tesco Extra and Primark.

He remains in a serious condition.

A 16-year-old boy, a 16-year-old girl and two 15-year-old boys, all from Canterbury, and a 17-year-old boy from Margate were arrested earlier this week as part of the investigation.

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

They have been released on bail pending further enquiries.

Canterbury MP Rosie Duffield - who branded the attack a "shameful stain" on the city - has since helped the victim's family get to the UK.

Officers are continuing to appeal to witnesses or anyone with information to come forward. If you have information that may assist the investigation and have yet to contact police please call 01843 222289, quoting reference 46/108995/19.
