A man was seen walking away from Mumbai's Naigaon railway station after allegedly assaulting a woman and pushing her onto the tracks, while other people were present on the platform. The incident has also raised questions about the bystander effect and why witnesses sometimes hesitate to intervene during emergencies. According to reports, a 20-year-old woman accused the man of repeatedly touching her inappropriately, even after she got off the train. When she hit him with her slipper, he allegedly struck her before pushing her between two coaches. The woman's left arm was caught beneath the train's wheels and had to be amputated below the elbow. She also suffered head injuries that required 16 stitches. The incident has brought attention to the bystander effect, a phenomenon in which people witnessing an emergency may hesitate to act because they assume someone else will intervene. Fear, uncertainty and concerns about the consequences can also delay action. Railway police arrested the accused, identified as 53-year-old Jitendra Hirmukhe, after examining CCTV footage. He was booked for molestation and attempted murder.
