In the hi-tech era of information overload,police have also turned to means like tracking social networking sites and cellphones to nab culprits. Of late,police have found success in locating those who were named as missing persons. On February 17,the Jama Masjid police station received a complaint from a family stating that their 25-year-old son had been missing with Rs 50,000,credit cards and gold. The investigation,police said,landed them on the Facebook page of the man. As police went through chat history,they found that the man had been in touch with 29-year-old married woman from Faridabad. According to police,in Faridabad,the team found that the woman had been missing since the same day the 25-year-old man was reported missing. A case had been filed by the womans husband at the Saran police station. The police team learnt that the woman had left behind her two children and in a note had said she was leaving as she was miserable with her husband. Technical surveillance of the mans phone revealed that he was in touch with a property dealer. Police questioned the property dealer to find that the two were living in a rented accommodation in Gurgaon and had changed their mobile phone numbers. But what they did not change was their phone handsets. The IMEI numbers of the phones led police to the couple,who were traced on March 8. Facebook also helped police track down a 20-year-old woman,who travelled with her friend a 22-year-old man to Jaipur claiming she had to write an exam there and then disappeared. The man returned to Delhi and along with the womans parents,he went to the police. Her Facebook page led police to track the IP address of a man in Jaipur and it was later found that the woman was living with him. Additional Commissioner of Police (Central) Devesh Srivastava said: The knowledge of computers among officers in the Delhi Police has paid dividends in working out these cases.
