Aviation regulator Directorate General of Civil Aviation on Monday suspended an IndiGo captain for three months for allegedly intimidating and threatening a wheelchair-bound senior citizen in a Chennai-Bengaluru flight on January 13, an official said.

During investigation, it was found that the pilot-in-command 'insisted' on an apology letter from the passengers -- the senior citizen and her daughter -- which further delayed the matter, detaining them for approximately 75 minutes after the deboarding began at the Bengaluru airport.

'It was established that the pilot-in-command's attitude towards the wheelchair-bound senior citizen passenger was intimidating, threatening and lacked compassion. The DGCA has suspended his license for a period of three months,' the official added.   -- PTI
