A 42-year-old man has been arrested after he allegedly smoked a beedi inside a lavatory onboard a Riyadh-bound IndiGo flight, a Mumbai Police official said on Tuesday raising concerns over security as the passenger had managed to pass through pre-boarding check-in at the Delhi airport.

He was handed over to the police by cabin crew after the Delhi-Mumbai-Riyadh flight landed at the city airport on Monday. Shockingly, the accused managed to sneak in a lighter and a beedi with him when he boarded the flight at the Delhi airport on Monday, the official said.
