PARIS : An administrative enquiry into the fatal roof collapse at Charles de Gaulle airport last year will blame flaws in the design and construction of the newly-completed terminal, officials at the Paris airport authority ADP said.

Confirming a report in Le Parisien newspaper, the officials said that several senior figures at the airport authority -- including possibly its president Pierre Graff -- were likely to be placed under judicial investigation after the enquiry team presents its findings on Thursday.
