The break-in attempt reportedly took place on Sunday night and an assessment was being made to find out whether anything was amiss, officials said here.
The French police is investigating the matter and the Indian Embassy in France is in touch with them.
India signed an inter-governmental agreement with France in 2016 for the procurement of 36 Rafale fighter planes in fly-away condition.
The planes are intended to meet the shortage in the IAF inventory.
