Police detained a man outside the House of Commons, London, Friday.
Scotland Yard said the man was arrested on suspicion of possessing a knife. No injuries reported.
The incident comes months after a man plowed a car into pedestrians on nearby Westminster Bridge and then charged into a Parliament courtyard, stabbing a police officer to death. In this case, the incident was not thought to be terror related, according to initial reports.
Pictures of a man being arrested outside of Parliament are surfacing online.
