ByThree days after a young woman was molested in the ladies compartment of a much-delayed Churchgate-bound local, the police have arrested a 19-year-old for the crime. Police said Pappu Yadav had entered the unguarded ladies compartment on Thursday night and groped the woman between Grant Road and Marine Lines stations. He was arrested from Kamathipura on Monday.Police said Yadav, who hails from Orissa, has been living in the city for over a year. He worked in a restaurant in Fort, which shut down a few days ago rendering him jobless.“He used to sleep on the pavement outside the restaurant. He was in an inebriated state on Thursday night and also when he was nabbed on Monday. We are interrogating him to find out if he is addicted to drugs,” an RPF official said.A CCTV camera installed at Grant Road station had captured Yadav loitering on the platform near the ladies compartment around 11.15 pm on Thursday. Based on the footage, several teams of the RPF, GRP and local police stations were on the lookout for Yadav.Based on a tip-off received from Kamathipura where Yadav was known to frequent, an RPF team nabbed him and handed him over to the GRP, said senior divisional security commissioner, Anand Vijay Jha.After the incident, the woman had given preliminary information to the police and returned home. Despite repeated attempts by the police to get in touch with her, the victim did not come forward to file the complaint.Asuo motu complaint was filed by the GRP under section 354 (outraging modesty) of the IPC and section 150 (e) of the Indian Railways Act. “We will attempt to convince the victim to come forward to record her statement. Her cooperation will help us get the maximum punishment for the accused,” said DCP GRP Deepak Devraj.The incident has also revealed the lapses in women’s security when the train service is affected by delays. The GRP commissioner has also directed the DCP to inquire and submit a report in eight days to find out why the ladies compartment was unguarded on Thursday.Prima facie, it was revealed that a signal failure near Kandivali station had interrupted train timings causing disruption in the schedule of police personnel who are on duty aboard trains.“We will be looking into how we can avoid the security personnel schedule can remain unaffected by train delays. We will be convening a meeting of various officials to find a mechanism to tackle this,” said Devraj.The probe will also inquire into whether there was an RPF or GRP personnel on duty on the platform near the ladies compartment when Yadav entered the train.
