Peterborough passport office has been evacuated this morning, Monday June 26.
Police and ambulance crews are at the scene in Northminister Road.
A police spokesman said officers were called to the scene at 10.26am after a suspicious package was delivered.
A cordon has been put in place.
It is the third time the passport office has been evacuated in the past month and a half.
The previous two incidents turned out to be false alarms.
