A Nicaragua-bound plane that took off from the United Arab Emirates (UAE) carrying 303 Indian passengers has been grounded in France over suspected "human trafficking", French authorities were quoted as saying by the local media on Friday.

According to a `Le Monde` newspaper report, the national anti-organised crime unit JUNALCO has taken over the investigation. Special investigators are questioning all those aboard and two people are in custody pending further examination, the Paris prosecutor`s office said in a statement.
