A teenager has been arrested on suspicion of murder following the fatal stabbing of a 21-year-old man at a shopping centre.

Police were called to Brent Cross Shopping Centre in north London at 6.45pm yesterday following reports of a group of males fighting.

Officers attended and found a 21-year-old man who had been stabbed.

Despite the efforts of officers, members of the public and ambulance staff, the man died at the scene.

Hundreds of people were evacuated from the shopping centre following the incident and the Metropolitan Police said it is likely there are a number of witnesses. 

Police say an 18-year-old man was arrested nearby on suspicion of murder, while a second man, also believed to be aged 18, has been arrested on suspicion of affray.

"Two people have been arrested and an investigation is already under way. We will do all we can to identify and bring to justice those responsible.

"The public can expect to see a heightened police presence in the area through the rest of this evening and in the days to come."
