More arrests in Oxford Street murder inquiry

Seydou Diarrassouba, 18, from Mitcham, south-west London, was stabbed in the heart after a fight broke out at a sports shoe store on London’s Oxford Street on Boxing Day.

Eleven people have already been arrested in the investigation. The arrests came after 17 suspected gang members were held in a bid to dampen “rising tensions” and prevent reprisal attacks. Investigators said a number of gangs were present at the time and were aware of people wanting to “seek retaliation or revenge”.

To pre-empt further violence, officers conducted a series of raids across the capital, arresting 17 people for a range of offences including grievous bodily harm, robbery, affray, intent to supply drugs, burglary, forgery and handling stolen goods. A large amount of cash was also seized.

The motive for the attack on Diarrassouba, who died from a single stab wound, is yet to be established.
