It's not something you want to hear at a festival, that someone has been stabbed and it's a sorry way for Wireless, the London urban music festival, to go this year.
Taking tips it would seem from the Notting Hill Carnival, known for it's potential violence as night falls on certain days Wireless have entertained two stabbings in it's midst this year.
Two men are now in hospital after being stabbed at around 9pm during headline acts Justin Timberlake and Jay-Z.
Both in their 20s one is said to be stable and the other critical. No one has been arrested yet.
