Stabbing near UK government office, Man arrested.

The offices of Britain’s interior ministry in London were placed on lockdown Thursday after a man was stabbed on the street outside, in a knife attack UK Home Secretary Priti Patel described as “horrific” and “unprovoked.

“Police were called to Marsham Street, where the Home Office building is located, on Thursday afternoon “following a report of a man with a knife at the location,” London’s Metropolitan Police said in a statement.

They attended to one man with knife injuries and arrested another “on suspicion of grievous bodily harm” who was taken into custody.

Eyewitness Gareth Milner, who was sat on a wall outside the Home Office eating lunch, said he saw “a number of armed police” arrive on the scene and enter the building.

“Sometime later a gentleman was escorted out by paramedics with what looked like dressing pressed to his face, which looked quite bloodied, and his shirt was open, I could not tell if blood on body was from face,” he said.

Police however said the incident is not believed to be terrorism-related.

British police recorded a total of 40,577 offenses involving a knife or sharp instrument last year 10,000 more than in 2011 while knife offenses have risen for five consecutive years.
