An engineer who worked on a UK nuclear project was quizzed on suspicion of being a spy after he returned to the UK from Russia.  

Mario Zadra, a 67-year-old Italian national, who worked as an engineer on the Hinkley Point C project from 2020 to 2023 from their headquarters in Bristol, was questioned by counter-terrorism police after he flew into Heathrow airport on April 12, 2023. 

It was reported that potentially sensitive documents were found in his possession and were seized by the authorities to prevent them being ‘used to carry out a hostile attack’. 

Zadra was arrested under Schedule Three, which gives police the power to search, question, and detain a person to determine whether they are engaged in hostile activity, Burnham & Highbridge Weekly News first reported. 

Hinkley Point C is currently constructing two new nuclear reactors, which will provide zero-carbon electricity for around six million homes, and is expected to cost a massive £46billion. 

Zadra was later dismissed by his employer, Alten Ltd, a supplier for EDF’s Hinkley Point C – settling for more than £37,000 in an employment tribunal, local media reported.

Counter terrorism police retained Mr Zadra’s hard drives for national security reasons. He was not charged with any offence. 

A spokesperson for Hinkley Point C said: ‘Hinkley Point C takes information security very seriously and there are rigorous measures in place to protect sensitive data. 

‘This individual did not have access to sensitive nuclear information. The information he removed was outdated. 

‘Allegations made by this person were thoroughly investigated and independently reviewed. His contract with Alten Ltd ended as a result of increasingly inappropriate and disruptive behaviour.’ 

The Met police and the Home Office have been approached for comment.
