Emirates flight EK505 from Mumbai to Dubai was detained as two passengers were escorted from the plane.

Indian police held a Dubai-bound Emirates flight in Mumbai for around four hours, detaining two passengers for questioning.

Emirates flight EK505 was grounded minutes before takeoff on Sunday morning, after airline staff received an anonymous telephone call alleging two passengers were members of the Pakistan-based militant group Lashkar-e-Taiba, Agence France-Presse reported, citing an airport official it didn’t name.

According to an Emirates statement, a male passenger and his wife were handed over to local authorities. Emirates said that the plane was eventually allowed to depart with all remaining passengers.
