MUMBAI: A 20-year-old youth, who procured six SIM cards from UP in fictitious names and used in the kidnapping of a seven-year-old boy, was arrested by Nehru Nagar police all the way from Varanasi.On February 2, the boy, a resident of Sable Nagar in Kurla (East) was playing with his friends when the accused Kishankumar Laccheram lured him with the promise of an ice-cream and kidnapped him. His parents searched the entire area and finally filed a missing complaint next day. “The same evening the victim’s father got a call on his mobile stating he should cough up Rs 15 lakh if he wanted his son back safely,” said Shahji Umap, deputy commissioner of police (zone 6).The boy’s father, who is in the catering business in Dahisar, immediately approached the police. During investigations, police found the number from which the accused called the victim’s father was switched off. Moreover, it was registered in a fictitious name and address. A day later, the man called from another number and asked about the ransom. As per the plan, the victim’s father started bargaining, saying he was a small businessman and would not be able to manage Rs 15 lakh post-demonetisation. “For two days he bargained and brought down the amount to Rs 5.5 lakh.On February 6, the accused asked him to come to Varanasi with the cash and call. It was very difficult to trace the accused as he was using six different SIM cards to call up the complainant and after every call he would switch off the phone,” said Pramod Khorpade, senior inspector, Nehru Nagar. Finally, police on Wednesday laid a trap and arrested Laccheram when he came to Varanasi station with the boy to collect the ransom.
