A 17-year-old boy has been arrested after two people were hurt during a robbery in central Ipswich.

Suffolk police were called to reports of disorder near to St Francis Court in Franciscan Way at around 6.50pm yesterday evening.

A group of suspects assaulted four victims, stealing a moble phone and a bank card in the process.

The four victims – a man and a woman in their 40s, and a man and a woman in their 20s – were taken to hospital for a check-up. The two older victims sustained minor injuries.
