Mumbai: The American commercial aircraft remained grounded in Mumbai even as a team of intelligence agency officials started questioning the 11-member crew on February 4 morning.

"Though the Indian Air Force (IAF) cleared the crew around 02:00 hours (IST), Intelligence Bureau (IB) has started questioning them only this morning," top government sources in Mumbai and New Delhi said.

The IAF had forced the Boeing 757 of Conco Corporation on way to Male from Karachi to land in Mumbai as the cargo plane violated the air space, sources said.
