Police investigating the murder of a father at a bus stop in south London have arrested two more men.
John Nii Kacsu Abbey, 26, a local boxer known to friends as King, was stabbed in Croydon on Thursday evening in front of his three-year-old daughter.
Mr Abbey was on his way to nearby Mayday Hospital to see his wife and newborn son when he was stabbed.
Police said two unnamed men, aged 36 and 39, were arrested early on Sunday morning in a “pre-planned operation”.
Police are also trying to trace a woman who administered CPR to Mr Abbey just moments after he was stabbed.
Det Ch Insp Cliff Lyons said: “She was present with John Abbey and his little girl performing CPR on the victim before paramedics arrived. She may have vital information that could help in the investigation.”
Mr Lyons described the woman as Asian and said police do not know whether or not she knew the victim.
A 22-year-old unnamed man who handed himself in to police on Friday also remains in custody on suspicion of murder.
Police have continued to appeal for other witnesses to the stabbing on the busy stretch of London Road opposite the Lidl supermarket to come forward.
They are particularly interested in speaking to two teenage boys who were at the bus stop when the stabbing took place.
Officers have found a number of knives in the area and were also reviewing CCTV footage from a number of cameras.
Police said Mr Abbey’s three-year-old daughter, who was unhurt, watched paramedics try to save her father after the attack.
A post-mortem concluded that the victim died of a single stab wound to the heart.
Mr Abbey, who is originally from Ghana, was taken to the same hospital at which his wife had earlier given birth, but was pronounced dead an hour after the 1815 GMT attack.
