Sangeeta Dubey had just boarded a 2.04 pm Dahanu-Churchgate fast local from Vasai Road. It was a daily routine - travelling in a second class apartment to ferry official letters and files to the Government Railway Police (GRP) head office in Wadi Bunder -- for Dubey, who works as a police naik with the GRP.Just as the train pulled out of the Borivali station around 2.21 pm, she noticed the commotion in the first class. A drug addict, later identified as Rajesh Vishwakarma (25), had entered the ladies compartment and was troubling the three women sitting there.Despite protests, Rajesh sat close to one of the three. As the woman put some distance between Rajesh and herself, the drug addict started stripping and caught one of the woman commuters by her hair. The other two women froze and stood in the corner. Commuters of the second class, which is sealed off from the first class with horizontal steel rods running up to the ceiling of the compartment, could do little to help. Some started yelling for help while others pulled the chain - but nothing happened as the train driver has express instructions to stop the train only at a station.Dubey knew she had to something - and do it fast."We had to do something there and then to help the woman who was fighting off the man alone. We were telling her to hit the man who by then had pinned her down near the partition. With some difficulty, the woman managed to push the man away who was trying to tear her clothes and came close to the partition."The woman pushed Rajesh away and ran towards the partition. "It seemed like the man was possessed - he could not see anything but the woman. He followed her towards the partition."That was Dubey's moment. She put her arm through the iron rods and grabbed Rajesh. "I managed to catch hold of his hair and pull him close to the partition," she told Mumbai Mirror.Dubey, a state-level kabaddi player and national-level Karate player, grabbed Rajesh in a chokehold. "But I was finding it difficult to hold him as he was trying himself with all his strength. Another commuter removed her scarf using which we tried to tie him up to the rods of the partition."These women held Rajesh off until the train halted at Andheri station and commuters of other compartments and the GRP came to their rescue. Dubey suffered bruises to her right arm.This is not the first time that Dubey's bravery and quick thinking has won accolades for the GRP. In 2012, she was felicitated by her office for her help in nabbing a Bihari gang of bag lifters who had created a menace at Kurla Terminus. Dubey posed as a woman in distress to catch the gang members red-handed - she told one of the gang members that she was from Bihar and had eloped from her house with her lover but was stuck in Mumbai as he had deserted her. When the gang member came to meet her at Bandra station, he was arrested leading to the busting of the gang.It is for this reason that Dubey's 18-year-old daughter - she has a 14-year-old son too and her husband runs a stationery shop in Dahisar - calls her Lady Singham.
