Mother's plea to catch 'devoted' family man's killers
The mother of a man stabbed to death outside a central London pub has said the "senseless" attack has robbed the family of a "devoted" father and son.
Christopher Foster, 34, was a single parent to a four-year-old girl and was "juggling work, childcare and parenthood".
He was stabbed at about midnight on Friday in Borough High Street, Southwark, as he smoked a cigarette.
Police believe the law firm worker was not the intended victim.
Mr Foster, of Walworth, south-east London, was with a male friend in an alleyway outside St Christopher's Inn.
A post-mortem examination found he died from a single stab wound to the back.
In a statement, Jean Foster said: "Chris was a devoted dad, a single parent juggling work, childcare and parenthood.
"This was a senseless unprovoked attack and the family feel robbed of a good son and brother.
"Our family are paying the price for someone else's actions, whilst they are still walking around. Chris will be forever missed.
"We can't bring Chris back but hopefully we will get justice for his daughter Christina who, at four years of age, cannot understand why Daddy has left her."
Met Police officers will return to the scene of the stabbing on 6 December, a week after the murder, to hand out leaflets about the incident and appeal for information.
Det Ch Insp John Sandlin said: "At this stage of our investigation, we believe this to be a case of mistaken identity.
"Mr Foster was stabbed as he stood halfway down the alleyway with his back to the suspects.
"Five of the suspects then carried on down the alley and were involved in a separate altercation with another male, who managed to get away."
A woman, 32, was bailed after being arrested on suspicion of assisting an offender.
