Maria said his stint in traffic department had helped him in getting the first clue behind the conspiracy that culminated in the March 12, 1993 bomb blasts in the financial capital in which over 250 people were killed.
The Commissioner was speaking at a function organised to mark the golden jubilee of Mumbai Traffic Police's Training Institute in Byculla here.

Eight policemen, five retired cops and five people assisting the department in managing traffic in the city were felicitated on the occasion.
Recalling the expertise he gained during his stint in traffic department, where he was Deputy Commissioner of Police in 1993, Maria said he stumbled upon the first clue related to the blasts when he found an abandoned scooter laden with RDX.
In 1992, Maria was moved to Mumbai as DCP (Traffic) from Raigad, where he was Superintendent of Police.
"During the probe we come across a scooter that gave me the first clue in the case. Using the proficiency I gained in the traffic wing, I reached absconding accused Tiger Memon's house with the help of the abandoned scooter.
"So the credit for cracking the 1993 blasts goes to traffic department too," said Maria, who played a key role in arresting most of the accused and unearthing Pakistan's role in orchestrating the explosions.
