Britain's Home Office building has been cordoned off by police after a man was found with stab wounds in the area.
A Reuters photographer saw a man with facial injuries and blood on his front being led from the heavily guarded Marsham Street building in central London on Thursday afternoon.
London's Metropolitan Police were called out to the location where officers found a man with knife injuries.
A police spokeswoman said it was too early to say whether the incident was linked to the Home Office but there was no suggestion it was terrorism-related
The Met initially said the victim's injuries were being treated as life threatening but later said the injuries were not life threatening.
One man has been arrested on suspicion of grievous bodily harm and taken to a police station.
