A man from Burwell is due to be sentenced on the 27th April for making a 'microwave bomb' which brought Cambridge city centre to a standstill.
Last month Robert Baker, 27, pleaded guilty to placing a suspect device in a microwave.
On the 27th September 2011 military bomb experts were deployed from RAF Wittering after Baker, of Toyse Lane in Burwell, placed a plastic drinks bottle containing copper piping inside a microwave at Wellington House.
The offices, which are on East Road in Cambridge, were evacuated along with parts of Anglia Ruskin University. Hundreds of office workers and students were locked out for six hours while police searched the area.
Sentencing is expected to begin at 11am.
