Maharashtra ATS has arrested one person who had allegedly stolen a two-wheeler used by terrorists to plant a bomb in Mumbai’s Zaveri Bazar on July 13 when serial blasts left 27 people dead in the city.

Sources in the Union Home Ministry said the thief had been detained on Sunday and was placed under arrest late on Monday night.

The development was seen as no breakthrough by the ATS team of Maharashtra which was probing the triple blasts that took place in Zaveri Bazar, Opera House and Dadar bus stand on July 13 last.

The sources said the vehicle thief may not be knowing about the terror groups which had planted the bomb at the crowded Zaevri Bazar, a place which claimed nearly 10 lives on the fateful day.

The security agencies had earlier questioned the owner of the maroon colour Honda Activa bearing number MH—01—AS 718, which was found very close to the blast site in Zaveri Bazaar.

Police had earlier detained one Arjun Singh, an employee of a Gujarati businessman, after they found that another damaged scooter parked at the same blast site belonged to Singh. He told the police that his scooter was stolen hours before the blasts.
