A teenage shop supervisor has been stabbed after tackling three thieves at a shopping centre in north London.
Forensic examinations are being carried out on the upper floor
Rudy Takkou, 19, was injured at Wood Green Shopping City on Wednesday evening in a service area closed to the general public.
He was found by a colleague and taken to hospital for surgery. His condition is described as stable.
Michael Thompson, the centre's manager, said it was thought the suspects may have been involved in shoplifting.
He added that security at the centre would be reviewed.
He said: "The altercation took place on the first floor and took place in a service corridor.
"One of the shop staff was stabbed as a result of the altercation and the youths - we believe there may have been up to three of them - ran off.
"We will look to see if improvements have to be made based on what happened."
Police said Mr Takkou was attacked at about 1715 BST.
Shop assistant Martin Inoussa, 21, said: "I was in the store as normal and I think I heard some screaming at about five o'clock.
'Outgoing and enthusiastic'
"We saw some security guards going upstairs and then later on they told us to close up."
The emergency services were alerted and the shopping centre was evacuated. Some roads were closed and buses diverted.
It is not known whether Mr Neofytou knew his attackers.
Moss Bros, which owns the Designer Outlet store where Mr Takkou was employed, said he had been with the firm for two months.
The company said he was "well liked by all those who deal with him, who describe him as outgoing and enthusiastic".
No-one has been arrested and CCTV footage of the area is being examined.
The upper floor of the shopping centre remains closed as forensic officers carry out investigations.
Anyone who might have seen the suspects - described as three black men - is asked to contact police or Crimestoppers.
