The Congress on Wednesday alleged that DRDO official Pradeep Kurulkar, arrested on charges of providing confidential information to a Pakistani agent, was an "active RSS volunteer".

The DRDO official was arrested last week by the Maharashtra Anti-Terrorism Squad (ATS). The Congress' attack came a day after a special court in Pune extended till May 15 the police custody of Kurulkar after observing that the charges against him were serious and custodial interrogation of the accused for a further period is unavoidable for a thorough probe.
