Documents and money have been stolen from an office used by Indian military personnel near Paris, a French prosecutor said on Wednesday, with the break-in thought to be linked to India’s purchase of French Rafale fighter jets. The robbery took place overnight Saturday-Sunday in Saint-Cloud, a suburb west of Paris, near the offices of France’s Dassault Aviation, which is building 36 fighter jets for the Indian military under a highly controversial contract. An investigation has been opened, a source in the local prosecutor’s office told an international news agency on the condition of anonymity, confirming that “documents and money” had been taken from a safe. A separate police source said the site was “classed as sensitive” and security services were alerted early Monday by an employee of Dassault Aviation. Indian news agency ANI, citing unidentified Indian Air Force officials, reported that the robbery occurred at the office used by the Indian Rafale project management team. Military personnel in the project office are responsible for overseeing the production schedule for the jets as well as training for maintenance and flight operations, it said. The Hindustan Times newspaper suggested the break-in could have been a spying attempt on a $9.4 billion arms purchase that has dogged Indian Prime Minister Narendra Modi since it was signed in 2016. The opposition Congress party has accused Modi of corruption and favouritism in handing the deal to Dassault and stipulating that the French group had to work with a conglomerate owned by Indian tycoon Anil Ambani.
