Police raided a house in London last night searching for a man wanted for questioning over a murder in Oxford.

Devon McPherson, 42, known locally as Jay, was stabbed in the neck after an argument with a man in Ridgefield Road, East Oxford, shortly before noon on Monday, May 18. He collapsed outside the Regal nightclub and later died.

Police released a photograph of an unnamed man, known in Oxford as Champagne, wanted in connection with the murder.

Last night, officers from Thames Valley Police and the Metropolitan Police raided a house at Catford, in south-east London, as part of their investigation.

Police spokesman Claire Gourlay said no evidence was found to show he was living at the house.

On Tuesday night armed police swooped on the towpath of the River Thames at Donnington Bridge, in Oxford, after an anonymous tip-off that the wanted man was sleeping rough, but no trace was found.

Anyone who knows where he is should call police immediately on 08458 505505 or Crimestoppers on 0800 555111.
