Stabbing victim is named

The 26-year-old boxer from Croydon, south London, was also known to his friends as King, a Metropolitan Police spokesman said.

A 22-year-old man is still being questioned by police over the murder in west Croydon on Thursday evening.

The victim was stabbed as he travelled with his daughter to the nearby Mayday hospital where his wife had given birth hours earlier. His little girl was left watching in horror as paramedics desperately tried to save his life on the pavement.

Detectives said Mr Abbey became involved in an argument with a second man, believed to be a former colleague, before the fatal blow was struck.

The 22-year-old was arrested on suspicion of murder after handing himself in at a south London police station.

Police are also hunting two teenagers wearing hooded tops who fled the scene and may have been involved in the scuffle. A post mortem examination revealed the victim died of a single stab wound to the heart.

Security guards at a nearby office described how they took the little girl away.

One staff member said: "I said she shouldn't be watching something like that, I asked around to see whose child she was and somebody said she was the victim's, so I took her away into our building."

He said that the three-year-old was "in shock, her eyes were wide open". She was muttering under her breath occasional words like "mum" and "Mayday".
