The leader of Luton Borough Council Hazel Simmons has told Heart she's ANGRY about the violence that broke out in the town on Sunday.
She said: "We know there were people coming in from outside the town who thought it was ok to come into the town and create a violent exhibition after what was a fantastic family day. I'm just so angry and appalled at it."
Police say the Carnival itself, which was Luton's 40th passed peacefully and calmly.
But two hours after it finished, violence and fights broke out in St George's Square, and four people were taken to hospital with stab wounds.
Videos have been shared widely on-line, showing missiles being thrown at police, who had to use batons to break up the fighting.
