A £20,000 reward is now on offer for anyone who can help identify those responsible for the murder of Malachi Brooks.

Two years on from the stabbing death of the Battersea man, police have also released footage that they hope will help catch his killer.

Malachi was was attacked on March 28, 2017 at approximately 1.10am in Surrey Lane.

Four men wearing balaclavas, hoods/face coverings pulled up in a car before three of them got out and stabbed Malachi before getting back in the vehicle and making off.

When the emergency services arrived, Malachi was found suffering from stab injuries, efforts were made to save him but sadly he died at the scene at 1.55am.

A post-mortem gave his cause of death as a stab wound to the heart.

DCI John Massey, from the Homicide and Major Crime Command leading the investigation, said: "We remain committed to bringing Malachi's killers to justice. His family are still grieving, every birthday every Christmas is made even more difficult knowing that his killers have not yet been identified.

“We know that Malachi's attackers had been driven to Surrey Lane to commit the murder and driven from the scene.

"The car used was then abandoned a mere 20 minutes after Malachi was killed, with Popatpotra, Rahmam and Preddie later found responsible for destroying that evidence.

"I am sure that there are people who Malachi’s murderers are, - most likely those in Tooting or wider South London - have information to help us solve this case."

A Nissan Micra was abandoned on Weir Road industrial estate at 1.20am the night of the murder and was set alight at 4.10am the next day.

The burning of this car destroyed any possible evidential fingerprint and DNA connection being established between the vehicle and the murderers.

Three men have since been jailed for perverting the course of justice and arson offences, relating to the car used in Malachi's murder.

Abdul Popatpotra, 27, of Totterdown Street, Battersea and Ashrafur Rahman, 23, of no fixed address were each sentenced to 21 months imprisonment after they were convicted of arson, with Rahman pleading guilty to perverting the course of justice.

Another man, Joel Preddie, 20, of Chantry Way, Mitcham was found guilty of perverting the course of justice and was jailed for four years.

Despite these convictions, Malachi's killers have never been caught and the Met is now offering a £20,000 serious crime reward for information that leads to the identification, arrest and prosecution of the person or persons responsible for his death.

Malachi's sister, Rashaune, said she has failed to understand how this could have happened.

"Every day I ask myself ‘why my brother," she said.

"Malachi was not a gang member and did not cause any harm to anyone. Malachi was trying to make something out of life.

"Words cannot explain how angry I feel that no justice has been served and the people that were involved are living life as normal.

"The pain and grief my family have gone through with Malachi being murdered has caused so many problems. Not only have we lost Malachi but it has split up the family.

"We are all finding it hard to deal with our emotions which is causing a huge effect."
