etectives investigating the “cowardly” murder of a teenage West Ham fan are asking an anonymous caller who may hold crucial information about his killers to get back in touch.
Sami Sidhom, 18, was stabbed to death in Chestnut Avenue, Forest Gate on April 16, 2018.
Sami – studying history and law at Queen Mary University – died in what is believed to be a case of mistaken identity.
A £20,000 reward has been offered by police for information leading to the conviction of those responsible.
Ten males aged 15 to 35 have been arrested but none charged.
Detective Inspector John Marriott, from the Met’s Serious Crime Command, today appealed to one person in particular to come forward.
They have previously provided several anonymous tip-offs but not spoken directly to officers.
He said the person could have vital information which could help bring Sami’s killers to justice.
DI Marriott said: “I understand how daunting it can be to come forward after such a terrible crime but investigations like this rely on the bravery of witnesses who find it in themselves to do so.
“My officers are here to provide whatever support we can to anyone who is willing to tell us what they know.
“Sami’s family have been devastated by the senseless loss of their son. For three years they have had only questions, but no justice.
“I urge anyone who has information about Sami’s murder, but in particular the person who has reached out anonymously before to provide key information, to contact us.”
Sami’s father, Samer Sidhom, added: “My only son, Sami, was stabbed to death near his home as he returned from watching a football game of his favourite team, West Ham. He was only 18.
“Sami was a wonderful son. He was a kind young man who always tried to help his family, friends and colleagues, and was respected by everyone who knew him. He did everything right. He fought hard to win his place in society and some cowards in the dark stabbed him in the back.
“My son’s killers are still walking the streets free of conviction or charge.
“I need you to provide the evidence to convict them. You know who you are and you have a choice. A choice to be someone that hides in the dark, or a brave person who sets the record straight.
“If you know the killers you already know they killed a perfectly innocent person for no reason whatsoever.
“He has done nothing to anyone; he was never involved in anything and had nothing to do with his killers. The only person that would stop them from doing the same to you is you.”
After watching the football match in Stratford, Sami took a bus to Romford Road and set out on the last part of his journey by foot.
He made his way along Sebert Road and turned left into Cranmer Road. He then turned left into Capel Road before crossing over into Chestnut Avenue.
At the same time, CCTV shows a silver car approaching the end of Chestnut Avenue where Sami crosses. The same footage shows three men chasing Sami followed by the same silver car.
Following the attack, the silver car and another vehicle drive off.
Anyone with information is urged to call detectives on 020 8345 3715.
