Three boys aged 14, 15 and 16 were arrested yesterday on suspicion of murdering a surveyor who was stabbed in the chest during a mugging.
The youths were detained in dawn raids in the Ladywood, Hockley and Newtown areas of Birmingham by detectives investigating the death of Paul Tanner, West Midlands Police said.
The 23-year-old died in hospital earlier this month after being attacked as he walked home, following a night out. A police spokesman said: "Detectives investigating the fatal stabbing of Paul Tanner have today arrested three youths at different addresses in Birmingham in connection with the inquiry.
"The three have been arrested on suspicion of murder and for alleged offences of robbery."
Mr Tanner, from Northwood Street, Hockley, Birmingham, was attacked shortly before 1.45am on Friday March 4 in the city's St Paul's Square.
The stabbing was condemned by police for its brutality after it emerged that Mr Tanner was attacked despite handing over his wallet and offering no resistance.
