Dino Donaldson attacked Anojan Gnaneswaran in January 2024 after a row broke out about between two groups of men over a drug deal.

21-year-old Donaldson was found guilty following a trial at the Old Bailey and will be sentenced at a later date.

The court heard how he pushed his victim onto the railway tracks and stabbed him in the chest, abdomen and thigh.

Gnaneswaran was pronounced dead at the scene.

Jurors heard that two groups of young men arranged a deal of £50 for 10 MDMA tablets to be exchanged at the station on the evening of the 8th of January 2024.

Donaldson and three others arrived first just after 10pm, followed by 21-year-old Anojan Gnaneswaran around an hour later.

There was a disagreement between the two parties and Anojan called his brother, who then attended the station with two others.

The argument continued on the station platform before Donaldson became increasingly aggressive and pulled a long knife out of his waistband.

He chased the group and caught up with Anojan on the railway tracks where he stabbed him in the chest, abdomen and thigh.

Anojan’s brother dialled 999 and began CPR before paramedics arrived to take over. Despite their life-saving efforts, Anojan’s injuries were so severe that he passed away at the scene.

BTP detectives launched an urgent investigation and tracked Donaldson’s movements after the attack using CCTV as he fled through Twickenham to Kingston.

He then boarded the N87 night bus and its on-board camera captured him laughing and smiling less than an hour after Anojan was pronounced dead.

BTP’s search team found the knife and a black glove in a tree at the murder scene. Forensic examination found DNA belonging to Donaldson and Anojan on both items.

An arrest warrant was executed at Donaldson’s home address on the 11th of January where he was found hiding inside a cupboard.

BTP Detective Chief Inspector Paul Attwell said: “What started as an argument over a drug deal ended in a young man’s life being cut short by a remorseless thug.

“Donaldson showed his true colours as a coward by arming himself with a knife that night. His cowardice has continued by never accepting responsibility and admitting his crime – thankfully the jury saw through his lies.

“He will live the rest of his life knowing he has taken someone else’s, and when he’s sentenced he will learn that he has a long time behind bars ahead to mull over his actions.

“While no verdict can ever compensate for the loss of Anojan, I hope today’s outcome provides his family with some sense of closure. Thanks to our extensive investigation, justice has now been served to the man responsible for killing their loved one.”

Anojan’s family have paid tribute to their “much-loved son and brother”.

They said: “Anojan was in his third year at university studying accounting and finance, and he was so excited for his future.

“He excelled at all sports and had achieved first-dan black belt in karate – he competed in the World and European championships in karate, and we will all miss him so much.”
