Police carried out a controlled explosion near to the North Korean embassy in London on Monday night.
The details of the night's events in Ealing were given in a statement made by Metropolitan Police.
It detailed how nearby homes were evacuated and roads were closed after officers were called to reports of an unattended package near the establishment on Gunnersbury Avenue.
The embassy was reportedly placed in lockdown while the police carried out their work, with a number of ambulances also on the scene.
The all-clear was given after the package was found to be non-suspicious.
The regime in Pyongyang maintains the embassy inside a seven-bedroom house in west London - a far cry from some of the more salubrious embassy buildings in the centre of the British capital.
