A day after the arrest of Balaghat regional transport officer (RTO) Ram Das Dakshya in a forgery case, police searched his office on Sunday and seized the documents related to more than 15,000 second-hand vehicles.
The vehicles were registered with Balaghat regional transport office since 2013.
"The documents are being scrutinised and all the police station in-charges of the district have been asked to carry out physical verification of chassis and engine numbers of all the 15,000 second-hand vehicles registered in past three years," said Balaghat superintendent of police (SP) Gaurav Tiwari.
He said the preliminary interrogation of the RTO indicates there was a big nexus between the transport department officials and vehicles' thieves in Balaghat district.
"Dakshya has been remanded to a five-day police custody and interrogation is on. More revelations are expected," he told HT over phone.
Dakshya, in-charge of Balaghat and Mandra regional transport offices, is accused of forged registration of a vehicle.
He was made accused after Balaghat police caught a four-wheeler in January, which was stolen from Nagapur town and registered at the Balaghat RTO by tampering with its engine and chassis number.
"During the course of investigation, it was found the stolen vehicle was fraudulently registered at Balaghat RTO in connivance with RTO officials," said Tiwari.
The police had booked six persons and arrested four persons, while RTO Dakshya and clerk Ram Prasad Gaud was on run.
On Saturday, Dakshya who was underground for the past 15 days, was detained near Gurra Check post in the district, when was trying to flee from the town in his private vehicle. He had also fitted a blue beacon atop on his private vehicle.
Police later arrested the RTO clerk from his work place.
Police also recovered Rs 15.55 lakh in cash from his vehicle. Seven mobile phones were also seized from his possession, police said.
The SP said Dakshya had also been booked under the Prevention of Corruption Act as he failed to reveal the source of the money which he was carrying in his vehicle.
