Feb 3 (Reuters) - India's aviation regulator said on Tuesday the wing tips of an Air India and an IndiGo aircraft scraped each other while they were taxying in Mumbai Airport.

"While AI2732 was taxying from C1 towards M4 for departure and IndiGo arrival flight was taxing joining B1, right wing tips of both the aircraft touched each other," the aviation regulator said, adding the aircrafts returned to the bay for inspections.
