A Bangkok-bound Air India flight from Mumbai with 154 passengers on board on Tuesday landed at the international airport in Delhi under emergency conditions after it developed a problem in its hydraulic system.

The pilot of Air India's flight 348 detected the technical glitch and landed the Airbus 310 safely at around midnight as emergency personnel were kept on standby, airport officials said.

All the 154 passengers on board are safe, they said.

"The pilot felt there was some problem in the hydraulic system and decided to land. The landing was normal. The aircraft was taxied to the technical area for a check," the carrier's northern India regional director D S Kohli said.

He said the "passengers would be flown to Bangkok and Tokyo in the evening and to other destinations thereafter."

They were being accomodated at the airport and and served refreshments. However, angry scenes were witnessed at the airport after around 125 passengers who were to take the flight to Bangkok from Delhi found themselves stranded and entered into heated arguements with Air India staff.

"The flight has been indefinitely delayed and they are not able to say anything," a passenger claimed.
