"I think it is for the Prime Minister - because he (Khadse) is a very senior minister of BJP, and the Home Minister (Rajnath Singh) to investigate through whatever agencies they want to use - RAW, IB or telecom department and come to the truth of the matter," he told reporters here.
Maharashtra Chief Minister Devendra Fadnavis had yesterday directed the Anti-Terrorism Squad (ATS) to probe the charge against Khadse, after AAP Spokesperson Preeti Sharma Menon levelled allegations against Khadse last week.
Chavan said the Maharashtra government should assist the central government in investigating the police and call records to go to the bottom of the matter.
"Whatever, the truth, the central government should go to the bottom of it. The matter not only concerns Maharashtra government. It should assist the central government investigation of the police record and telephone records," he said.
However, Khadse had claimed he had documents to prove that his mobile phone was hacked to show as if calls were made, and added that he would hand over all the evidence in this regard to the investigating agencies.
