A man’s life was in danger after he was stabbed near British government offices in central London on August 15.
Police said they were called to Marsham Street where the Home Office (Interior Ministry) is located after a man armed with a knife was reported.
They found a man with knife injuries which were being treated as life-threatening. Another man was arrested at the scene on suspicion of causing grievous bodily harm.
A Reuters photographer saw a man with facial injuries and blood on his front being led from the Home Office building.
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.
“Enquiries are ongoing into the exact circumstances of the incident,” police said in a statement.
