The investigation into the murder of software engineer Esther Anuhya has revealed a system of code words used by auto and cab drivers to identify and cheat vulnerable passengers arriving at the Lokmanya Tilak Terminus (LTT) in Kurla.The next time you hear the words ‘bater’, ‘mangloo’ or ‘GPL’ while hailing a ride outside the station, beware. ‘Bater’, as the Indian quail is called, is a code the drivers use to alert each other about a woman travelling alone and looking for an auto or taxi. ‘Mangloo’ refers to a person who appears to be new to Mumbai, perhaps visiting the city for the first time.‘GPL’, which translates into a kick on the rear, is used by autorickshaw drivers and cabbies who stop their vehicle in the middle of the journey on the pretext of a breakdown. They then ask the passengers to hire another ride. This happens especially when passengers have paid the fare at prepaid counters.Anuhya, who lived in a hostel in Andheri, had gone to her home in Hyderabad for the Christmas break. She returned to Mumbai on January 5 and was last seen taking an auto outside the Lokmanya Tilak Terminus. Her burnt body was found off the Eastern Express Highway on January 16.“Once the target has been identified, the drivers decide who will ferry the passenger. Normally, they share the money,” a Crime Branch officer, who didn’t want to be named, said.The most common trick is to take the unsuspecting passengers via longer routes, and meters of such cabs and autos have been tampered with. “One of their most common tactics is to claim the passenger paid them Rs 100, when they may have actually handed the driver a Rs 500 note,” the officer said.Police have also learnt that rogue cabbies and autos at the LTT are split into two groups – Hindustani and Kargil – and both groups are at loggerheads.Additional Commissioner of Police (Crime) Niket Kaushik confirmed the code word tactic, and said: “Our investigation revealed many such words.”
