Five Air France employees have been arrested following violent scenes at the company's headquarters in Roissy last week.
Workers were protesting against mass job cuts when two managers had their clothes ripped, with one being forced to flee over a fence.
Hundreds of workers were protesting against plans to cut 2,900 jobs, increase pilots' working hours and reduce the size of the fleet, all designed to cut costs by €1.8bn over two years.
Two managers in particular were targeted - human resources manager Xavier Broseta and senior official Pierre Plissonnier.
