The person stabbed and killed at East Croydon train station on Monday (January 27) has been named as 16-year-old Louis Johnson.

The violent attack happened around 4.30pm on the over bridge at the station, which was busy at the time, and lasted around 40 seconds.

British Transport Police (BTP) said that Louis entered East Croydon Station through the Ruskin Square ticket barrier, and was attacked minutes later.

A spokesperson described how while Louis was on the over bridge in the station, he met someone who immediately pulled out a knife and stabbed him.

Emergency services were called at around 4.45pm, but despite the efforts of medics, including an air ambulance team, he died.

Detective Chief Inspector Sam Blackburn described the killing as "senseless" as he offered his condolences to Louis's family:

"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," DCI Blackburn said.

He added a direct appeal for information from the public in the hopes of tracing those responsible.

"Many passengers" or other members of the public will have likely seen the attack take place, the detective said:

"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.

"Importantly, if you have any mobile phone or dashcam footage of the East Croydon area either just before, during or after the attack - we want to hear from you."

The boy's family have been told, and are being supported by police.

No arrests have been made so far, police said.

BTP said there will be increased patrols in and around the station on Tuesday.
