Up to 30 men were believed to have been involved in unrest in Malvern Hill Road
A 19-year-old man was stabbed in the chest during a brawl involving up to 30 men in Birmingham, say police.
The man went to hospital on Friday evening and was in a critical but stable condition after surgery.
Officers said 15 minutes earlier police received "numerous calls" to Malvern Hill Road, Nechells, where the stabbing was believed to have happened.
Two 20-year-old men were arrested and bailed on suspicion of violent disorder.
Det Sgt Adam Hicklin said: "We know this was a targeted stabbing but at the moment we're not clear on the motive behind the attack."
