Pune (Maharashtra), Nov 20 (IANS): Exactly 15 months after rationalist Narendra Dabholkar was killed, the mystery about his killers continues unresolved.

Members of the Andhashraddha Nirmoolan Samiti (ANS), which Dabholkar founded, his family members, social activists and commoners Thursday gathered carrying banners and placards at the exact spot near the Junglee Maharaj Road, where he was gunned down Aug 20 2013, at 7.55 a.m. when he was on a morning walk.

The activists urged that the new BJP government at the centre and the state should step up efforts to nab the killers at the earliest.

The gathering paid homage to Dabholkar with songs and raised slogans demanding that the elusive culprits be nabbed as soon as possible.

In the past 15 months, Pune and Maharashtra police set up over a dozen teams of investigators to arrest the killers but have drawn a blank so far.

The ANS has been meeting top officials of the previous Congress-NCP regime and the new BJP government of Chief Minister Devendra Fadnavis to take action in the matter.
