A 25-year-old from Thamesmead was murdered after a revenge attack ordered by a convicted cannabis dealer descended into a "brutal" stabbing and hammer assault, a court heard.

Olamide Fasina, known as Ben or Trigger, bled to death after he was stabbed in the heart in Wolvercote Road on October 14 last year.

Mark Fenhalls, prosecuting, described how Steven Ngolo, 22, of Portmeadow Way in Abbey Wood, allegedly called from a telephone in his jail cell in Thameside Prison, urging revenge on Mr Fasina for robbing a low-level drugs runner known as "Kid" .

When Ngolo heard about the robbery "he went mad, he was cross, furious and urged the others to exact retribution," the prosecutor claimed.

Mr Fenhalls added: "He demanded, encouraged and urged a revenge attack on Mr Fasina."

However, a series of calls made from Thameside Prison on October 13 and 14, believed to be patched through by Ngolo's sister, were recorded by prison authorities.

Ngolo was using a prison phone which would only be used to call a fixed list of family members, but followed a "flawed" system whereby others could be added into conference calls.

This Is Local London:

Bliss Duodo, 22, of Edgington Road in Abbey Wood, Louis Henry, 22, of no fixed address, and Alvin Ansar-Baaphy, 23, of Old Dover Road, Blackheath, are all charged with murder and conspiracy to cause GBH.

Ngolo, 22, is also charged with conspiracy. All four men deny the charges against them. 

The jury were read the transcription from a telephone call sometime after 2pm between Henry and Ngolo.

Mr Fenhalls claimed: "Mr Henry says 'He is no more'.

"Mr Ngolo said 'When did you bug him'.

"That's the call in which Mr Henry tells Mr Ngolo that Mr Fasina is dead. 

"And he seems to be saying that he is with Mr Ansar-Baaphy and Mr Duodo."

The next day, Ansar-Baaphy and Henry fled to Leicester, the jury heard.

Henry then look a cab to Bognor Regis on the Sussex Coast, and was arrested in Gillingham in Kent, the prosecutor claimed.

Ansar-Baaphy was arrested in Luton, where "he was told prior to to his interview that his DNA was found on a blood trail at the scene."

The trial continues.
