At least four passengers of Chennai-Secunderabad Charminar Express were allegedly robbed of their jewelleries in Andhra Pradesh's Prakasam district.

One of the robbers, suspected to be on board the train, pulled the chain near Chirala at around midnight yesterday to stop the train, according to a spokesman of South Central Railway (SCR).

Some robbers then snatched the chains and other jewellery of the passengers through the windows in sleeper coaches, he said.
