Police said they rescued two persons, who apparently were taken hostage, from a restaurant in Imadol and arrested two persons for their alleged involvement in the case. Acting on a tip off, a team of security personnel raided the Mridal Bamboo House Restaurant yesterday evening and freed Ramraj Chaudhary (40) and Satya Narayan Chaudhary (30) of Chitwan. Police said they are interrogating the suspects--Nanda Kishor Chaudhary (40) of Bara, now residing in Imadole; and Mohan Chaudhary of Rautahat—by taking them in custody.
