Two men were taken to hospital after being stabbed in a heated brawl at London's Wireless festival yesterday evening.

The incident, which took place during Justin Timberlake and Jay-z's 'Legends of the Summer' performance, with special guest Rihanna, left both men in a critical condition.

One victim in his 20s has since been released from hospital, whilst the other, also believed to be in his 20s, is still in hospital but is said to be stable. No arrests have been made. [via BBC]
