Police seal off the scene after the killing of a teenager on Oxford Street in London packed with shoppers.
The 18-year-old was fatally stabbed in broad daylight during a fight between two groups of youths.
Police sealed off part of the street on what was one of the UK's busiest shopping days of the year.
SOUNDBITE: Detective Chief Inspector Mark Dunn, Metropolitan Police, saying (English):
"This is probably the busiest place in the United Kingdom right now and the busiest shopping day so it's been difficult really for us to piece together what's happened. But of course the flipside to that is that we probably have more witnesses than we normally have and I'm very much looking forward to them coming to speak with us."
About ten people have been arrested in the connection with the killing.
Three others have been held after another man was stabbed in the leg nearby but it's unclear if the two attacks are linked.
