Shoppers are expected to flock to one of Britain's busiest shopping streets on Tuesday, a day after two stabbings that left a teenager dead and a man with leg wounds.
Horrified shoppers saw a teenager stabbed to death in broad daylight yesterday as thousands of bargain hunters thronged London's Oxford Street.
As the West End shopping hub bustled, a fight broke out in its Foot Locker store leading to the 18-year-old's death at around 1.45pm.
Hours later a second stabbing took place on the same street just a few hundred yards away, leaving a 21-year-old man with non-fatal leg wounds.
Last night Scotland Yard said they had recovered a number of weapons from the first crime scene and arrested 11 people.
Three males have been arrested in connection with the second stabbing, which took place near Oxford Circus underground station at about 6.20pm.
Inspector Bruce Middlemiss, the duty officer for Westminster Police, said last night that shoppers should not feel unsafe but that police would conduct a "review".
"There is a high police presence here, we have a number of operations in place already for the shopping times because we were aware of the amount of people who would be here.
"We are going to back and review the intelligence for both incidents and see if we need to increase the police presence here but at the moment we are not concerned for ordinary members of the public who are shopping."
A white tent was erected yesterday in the street a few yards from the entrance to the Foot Locker store.
Police would not comment on speculation that the row which resulted in the south London teenager's death was over a pair of trainers. They said the fight had broken out after the youths began "arguing" in the shop.
Detective Chief Inspector Mark Dunne, the senior investigating officer from the Metropolitan Police's Homicide Command, said: "There appears to have been two groups of young people opposing each other and involved in this incident.
"It would appear at this stage there was a weapon involved that may well have been a knife but I can't confirm that yet.
"A number of weapons have been recovered from that scene, whether I have got the murder weapon I don't know. There's an assortment of items but no guns."
Amateur video footage posted on YouTube showed angry scenes outside the Foot Locker store as police held back remonstrating youths while paramedics attempted to revive the first stabbing victim.
Confused Boxing Day bargain hunters and tourists were coming up to the police cordon to take pictures and ask officers what had happened.
Shoppers could be seen going in and out of shops near the crime scene, such as Debenhams and Zara, but a number of stores were forced to close. Stores are expected to open as normal again today.
Richard Dickinson, chief executive of the New West End Company, which represents retailers in Bond Street, Oxford Street and Regent Street, said the organisation was "shocked" by the two stabbings but said such incidents were "extremely rare" in the area.
He added: "New West End Company is seeking rapid reassurance that the Metropolitan Police is adequately resourced for such events and have called for an early meeting with Deputy Mayor for Policing Kit Malthouse and senior operational Commanders to ensure such incidences and learnt from and not repeated."
The company reported £15m sales in the first three hours of the Boxing Day sales despite a drivers' strike on the London Underground.
