Dismissed police official Sachin Waze told an inquiry commission here that IPS officer Param Bir Singh had advised him not to indulge in the "illegal activity of collecting money" for anyone.

Singh, who surfaced in public after six months on November 25, is himself likely to appear before the Justice KU Chandiwal commission on November 29. The one-member commission is conducting an inquiry into Singh's allegations that Anil Deshmukh, then Maharashtra home minister, had asked police officers including Waze to collect Rs 100 crore from bars and restaurants in Mumbai.
