A charter plane grounded in France for a human trafficking investigation departed Monday for India with 276 Indians aboard, authorities said. The passengers had been heading to Nicaragua but were instead blocked inside a rural French airport for four days in an exceptional holiday ordeal.

Associated Press reporters outside the Vatry Airport in Champagne country saw the unmarked Legend Airlines A340 take off after the crew and passengers boarded the plane.

The regional administration said that 276 of the original 303 passengers were en route to Mumbai, and that 25 others requested asylum in France. Those who remained were transferred to a special zone in Paris’ Charles de Gaulle airport for asylum-seekers, it said. The passengers grounded in France had included a 21-month-old child and several unaccompanied minors.

The remaining two passengers were initially detained as part of a human trafficking investigation but were released Monday after appearing before a judge, the Paris prosecutor’s office said. The judge named them as “assisted witnesses” to the case, a special status under French law that allows time for further investigation and could lead to eventual charges or to the case being dropped.
