A fight broke out involving a large group of males at Westfield in Stratford, east London, and a man in his 20s was fatally wounded.
He was pronounced dead at the scene.
The attack happened in the middle of the afternoon in a busy area of the shopping centre called The Street.
Police said they believe two other males suffered minor injuries.
