Only two years ago, O’Connor was jailed for seven years for having a loaded revolver while in an Uber in London.
The 26-year-old was part of the Kennington-based drill group Harlem Spartans and also a member of a south London gang, who were involved in violent disputes with other gangs in Brixton, the Met said in 2023.
He was released from prison on licence but has now been recalled as a result of the knife offence.
O’Connor was produced at High Wycombe Magistrates’ Court on Monday, July 14, where he was sentenced to an additional eight months in prison.
Investigating officer Detective Sergeant Ed Crofts said: “O’Connor was located while officers were searching for those involved in a fatal road traffic collision on the M40.
“He attempted to make off from officers, and resisted arrest when the knife was located.
“He was arrested and charged within 24 hours and has now been jailed for the offence.
“He was also recalled to prison for breaching his licence conditions for an earlier offence, and I am pleased he is back behind bars where he belongs.
“We will never tolerate anybody carrying dangerous weapons in our community and will seek to bring to justice those that do so.”
A different man – Trad Almaghrabi, 23, from Harlington Road in Uxbridge – was charged with causing death by dangerous driving and causing serious injury by dangerous driving.
Police said the collision involved a black Volkswagen Golf and blue Mercedes AMG C250.
