No-frill carrier SpiceJet has begun an enquiry into an incident in which a differently-abled woman was off-loaded from its Kolkata-Mumbai flight yesterday after the crew claimed it was not safe to have her on board.

The airline, which expressed regret at the incident, said, "We are investigating the matter internally and action will be taken" in the matter in which Jeeja Ghosh, a 42-year-old teacher at Kolkata's Indian Institute of Cerebral Palsy, was offloaded after she had boarded the flight.
