A man was spotted on the roof of the New Zealand embassy in central London, sparking a large emergency response, reports say.
A section of Haymarket, near Trafalgar Square, was cordoned off outside New Zealand House shortly after 3.30am on Friday morning.
A man was reportedly seen at a height on top of New Zealand House on CCTV shortly, the news agency UKNIP reported.
Emergency services were called to the scene after the man was seen moving across the roof of the embassy building by security staff.
The London Fire Brigade, London Ambulance Service and Met Police were all seen at the scene overnight.
The LFB told the Metro newspaper they are no longer at the scene, and travel data site Inrix shows that the roads around New Zealand House have since reopened.
The Standard has contacted the emergency services for comment.
