Parliament is in lockdown and there is a heightened police presence on the estate, after an alleged intruder was reportedly tasered by armed police within the estate by Carriage Gates, having made it a few meters inside. Two police cars are now parked outside.
UPDATE: ITV’s Paul Brand has taken a photo of what appears to be the police holding the alleged intruder. The situation seems to be under control.
UPDATE II: The intruder has now been taken away in a police van, and the Metropolitan Police have released this statement:
“A man was detained and arrested by Carriage Gates inside the Palace of Westminster on suspicion of trespassing at a protected site, at around 11.55hrs on Tuesday, 11 December. A Taser was deployed. Enquiries into the circumstances continue.”
