Dozens of police cars raced to Kennington Underground station in south London at around 7pm.

The Met Police and London Ambulance Services are said to be on the scene.

Eyewitness pictures show traffic at a standstill and crowds amassed outside the station.

It is not yet clear whether the incident is linked to the terror attack in Westminister earlier today.

One witness wrote on Twitter: "Just now at Kennington station, police and ambulance in force, seem to still be looking for someone."

Another witness wrote: "Police cars and ambulances are swarming Kennington right now. Sat on a bus outside."

A third posted: "Something's happened at Kennington which is literally down the road from us. Staying in the flat tonight me thinks. Stay safe peeps."

Initial reports suggest someone was stabbed during an altercation outside the station.

Police have not made any arrests, according to reports.

The incident comes just hours after a knifeman mowed down a crowd of people outside the House of Parliament.
