A man has been arrested on suspicion of killing a father who police believe was murdered in case of mistaken identity.

Christopher Foster, 34, was attacked at about midnight last Friday outside St Christopher's Inn in Borough High Street, Southwark.

The law firm worker from Walworth, south-east London, who was single parent to a four-year-old girl, was stabbed in the back.

A 30-year-old man was arrested at midday on Friday.

He is being questioned at a south London police station.

Witnesses said they saw seven suspects wearing hooded clothing carrying baseball bats and at least one knife at the scene of the murder.

'Back to suspects'

Lead investigator 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, and this male's friend.

"The male friend received a hand injury but did not require hospital treatment.

"I would ask anyone with information about the suspects or any witnesses to please come forward."

Five of the suspects made off south down Borough High Street and tried to get into another bar, Belushi's. They then turned left and ran down Mermaid Court.

The remaining two suspects made off separately.

A woman, 32, has been bailed after being arrested on suspicion of assisting an offender.

Detectives will return to the scene of the murder a week on, between 23:00 GMT and midnight, where they will hand out appeal leaflets in the hope of tracing further witnesses and obtaining more information.
