Owen Dodds was airlifted to Newcastle's Royal Victoria Infirmary after the blast at his home at Ravenscleugh Farm in Elsdon on January 2.

After an extensive investigation by Northumbria Police the 29-year-old has now admitted a string of charges under the Explosive Substances Act.

Dodds admitted eight charges of making explosives and four counts of possessing explosives when he appeared at a plea and case management hearing at Newcastle Crown Court.

He also pleaded guilty to possessing two .22 ammunition cartridges and manufacturing a hand pistol – an offence which carries a minimum five-year jail sentence.

Dodds, whose hand was ripped apart in the explosion, admitted possessing hydrogen peroxide, sulphuric acid and potassium nitrate.

The charges relate to the production of improvised explosive devices, as well as modified timers, pyrotechnic fuses and possessing nails and modified pipes.

Dodds, flanked by two security guards in the secure dock at Newcastle Crown Court, leaned gently forward to say 'guilty' to each charge put to him.

The case was adjourned for the preparation of pre-sentence reports.

After the case Detective Chief Inspector Mick Paterson, who led the investigation, said: "Police were called to the farm on January 2 where the defendant had been injured as a result of an explosion, receiving injuries to his hands.

"A search of the farm revealed several improvised explosive devices and manufactured explosives and he was arrested."

Dodds was remanded in custody and will return to Newcastle Crown Court for sentence on June 9.
