A 16-year-old boy who was stabbed to death in front of horrified commuters at a London railway station in the ninth murder to plague the capital this year has been named by police as Louis Johnson.
Emergency services, including the London Ambulance Service and London Air Ambulance, scrambled to East Croydon station at 4.45pm yesterday afternoon.
Despite the best efforts of paramedics Louis was pronounced dead at the scene.
The force said the teenager entered the station via a ticket barrier on Monday afternoon and met the suspect 'who immediately pulls out a knife and stabs him'.
He died a short while later. No-one has been arrested.
A witness claimed they saw a man with a machete at the busy south London commuter station and then saw a person 'slumped near the ticket office' with 'blood everywhere'.

Detective Chief Inspector Sam Blackburn said: 'This was a senseless killing at an extremely busy time of the day, and my thoughts are with Louis's family at this painfully difficult time.
'For such a young man to lose his life in these circumstances is truly devastating, and I would like to reassure everyone that a thorough investigation is well under way.
'With that in mind, we continue to appeal for anyone with information to get in touch as a matter of urgency. The incident was over within a matter of 40 seconds, but I know many other passengers or members of the public would have seen what happened. If you have not already spoken with police, please get in touch.'
