YSRC’s North Andhra districts coordinator and former minister Kurasala Kannababu, along with party activists, took out a bike rally from Turangi in Kakinada Rural mandal to Karapa on Monday, demanding a CBI probe into alleged irregularities in DSC recruitment. Kannababu sought resignation of education minister Nara Lokesh, holding him responsible for the alleged irregularities. He called upon the government to release fee reimbursement arrears to colleges and provide a monthly stipend of `3,000 to unemployed youth. Meanwhile, Rajanagaram former MLA Jakkampudi Raja was placed under house arrest by police on Sunday to prevent him from participating in YSRC agitation programmes over alleged DSC irregularities and the demand for Lokesh’s resignation. He alleged that the CM was trying to protect his son over the alleged DSC irregularities.
