The accused policeman has been handed over to Anti-Corruption Bureau sleuths for questioning. He will be produced in court on June 4, ACB sources said.
Sonwal, who was on the run, yesterday surrendered before a court in Ajmer in connection with the case in which former Ajmer SP Rajesh Meena was arrested in April this year.
Meena was allegedly extorting monthly payments from officers in-charge of various police stations in the district through a private person, one Ramdev Singh. Both of them are now in police custody.
