The Central Bureau of Investigation (CBI) on Thursday arrested the kingpin of the NEET-UG paper leak case. The investigation team has detained Rakesh Ranjan aka 'Rocky' from Dhanbad in Jharkhand. 

As per the reports, Rocky is reportedly a relative of the mastermind Sanjeev Mukhia. The CBI had been tracking him since taking over the case. 

Earlier this week, the CBI conducted searches at 15 different locations at Bihar and Jharkhand, to gather evidence related to the case.

Rocky was produced in Court after the arrest and was remanded under the custody of the agency for 10 days.

Notably the agency has filed six FIRs in connection with the alleged irregularities in the medical entrance exam. One FIR in Bihar deals with paper leaks, while others from Rajasthan, Gujarat, and Maharashtra deals with the incidences of cheating and impersonation.

This year's exam took place on May 5 across 4,750 centers in 571 cities, including 14 abroad, with over 23 lakh candidates appearing for it.
