Ozzie Welsh, of Short Lane in Feltwell, near Downham Market, was charged with offences under the Explosives Substances Act 1883, which he had denied.

Appearing at the Old Bailey today (January 23), Welsh pleaded guilty to possession of explosives in suspicious circumstances, contrary to section 4(1) of the Act.

He pleaded not guilty to causing an explosion likely to endanger life or property, contrary to section 2 of the Act, which was accepted by the prosecution.

The charges related to an incident at Boughton Doctors Surgery on Chapel Road on Thursday January 28 2016 when a suspicious device was discovered at the premises.

Police were called after staff reported finding minor damage in the foyer area along with canisters and ball-bearings. A 100-metre cordon was initially put in place and specialists from the bomb disposal unit also subsequently attended.

Detective Chief Inspector Marie James, from the Norfolk and Suffolk Major Investigation Team, said: “The devices recovered from the surgery were later tested by specialists and found to be viable improvised explosives.

“While no one was injured, offences involving explosive substances are treated with the utmost seriousness and we will investigate these incident thoroughly.

Welsh has been remanded in custody to appear before Old Bailey on Monday 13 March for sentencing.
