In a top secret mission, a team of the Research and Analysis Wing tracked down an absconding accused in the Bangalore serial blasts case in Muscat, and sneaked him out of Oman, since India doesn't have an extradition treaty with that country.

Sarfaraz Nawaz, 32, who allegedly played a major role in financing the Bangalore blasts, had sought refuge in Muscat.

Investigating officials told rediff.com that a RAW team managed to track down Nawaz in Muscat. They added that Nawaz was 'smuggled into' Bangalore on a chartered aircraft.

The entire operation was so secretive that even the Air Traffic Control was taken aback when they received a message to help the chartered aircraft land at the Bengaluru [Images] International Airport.

After landing at the airport, officials of the RAW and the Intelligence Bureau called top Central Industrial Security Force officials and directed them to escort the passengers in the aircraft.

The officials handed over Nawaz to the Bangalore police, who are currently questioning him.

Abdul Sattar, the prime accused in the case, had revealed Nawaz's role in the serial blasts during his interrogation.

Nawaz was reportedly close to Riyaz Bhatkal, a key Lashkar-e-Tayiba [Images] operative, who later took over the charge of the Indian Mujahideen
