A £20,000 reward is being offered to find a gunman who killed a passing delivery driver and a 27-year-old man in gang-related violence in south London.

Guilherme Messias da Silva, from Brazil, died on Railton Road, Brixton, after being knocked off his moped while making the final delivery of his shift on Sunday 30 October.

The 21-year-old was hit at around 7.50pm by Lemar Urquhart, who was driving a white MG involved in a car chase at the time.

After getting out of the car, Mr Urquhart was chased by a gunman from a second car and fatally shot eight times. The gunman is yet to be found.

Crimestoppers is offering a £20,000 reward for information leading to the gunman’s arrest and prosecution.

Earlier this month at a hearing to open inquests into the deaths, Detective Inspector Jason Fitzpatrick told the court: "Identifying the suspects involved is proving difficult at the moment."

In a statement to police, Mr da Silva’s mother Rosangela said: "I am here to tell you how devastated and shattered I am by the premature death of my son who went to the United Kingdom in search of a better life for himself and our family.

"Unfortunately, Guilherme’s death happened in a tragic way, and it was caused by irresponsible people who deserve to be punished for taking away the life of an innocent person.

"My son was a calm, quiet and hardworking boy. My sadness goes beyond my soul for losing my beloved son."

Mr Urquhart’s parents have also urged anyone with information to come forward.

Alexa Loukas from Crimestoppers said: "It’s truly shocking to think that such violence could take place on the street in the early evening, taking away the lives of two young men.

"Our thoughts are very much with the family and friends of the victims, and the wider community affected.

"If you know something about this awful shooting – and are unable to speak to the police for whatever reason – Crimestoppers can help. We can pass on what you say whilst we guarantee you stay totally anonymous.

"Please tell us what you know. However small a piece of information may appear to you, it could be vital in helping to make a real difference in your community without ever having any comeback."
