"My 21 year old nephew was repeatedly stabbed in a brutal attack in London on Thursday night," wrote "The Royals" star. "The police & hospital are being fantastic. Thank you for all your messages. It is an appalling time for him & our family. The police will be appealing for witnesses."
According to the BBC, police did not confirm the identity of one of two victims to be Miles, but did say they believe a group of men got out of a vehicle and assaulted the two men before fleeing.
