An Indian businessman has been convicted of carrying out a horrific sex attack on a 15-year-old girl as she slept on a flight to Switzerland.

The 44-year-old married man attacked the teenager, who was sitting next to him, during the nine-hour journey from Mumbai to Zurich.

The perpetrator was on a business trip to Belgium when he carried out the attack in March.

The girl and the man had a brief, superficial conversation before the minor fell asleep.

The man then approached the victim and performed sex acts on her and himself.
