A section of the A3 Clapham High Street remains closed this morning following a stabbing incident that occurred late last night.

Police and emergency services were called to the southbound carriageway of Clapham High Street, between Bedford Road (Clapham North Station) and Aristotle Road, shortly after 9:15 PM on Thursday, 10 April.

The incident took place under the railway bridge, prompting a significant response from Metropolitan Police units and London Ambulance Service. Officers quickly cordoned off the area and launched an investigation into the circumstances of the attack. The condition of the victim has not yet been officially released.

Road Closures and Diversions

As a result of the police investigation, the A3 remains closed southbound, and a diversion is in place for several bus routes, including the 50, 88, 155, 322, and 345. Despite the closure, traffic is reported to be coping well.

Commuters are advised to avoid the area if possible and allow extra time for travel.

Police Appeal

The Metropolitan Police have yet to make any arrests and are appealing for witnesses or anyone with information to come forward. A police source said:

Community Reaction
