The arrested were identified as Ramesh Dahiya (35), a farmer, Amit (21), a wrestler who did his BA, Pawan (20), a state level boxer and Lalita, a 20-year-old housewife, M A Rizvi, Additional Deputy Commissioner of Police (Outer), said today.
A minor, a Class X student who is also a wrestler, was also detained in connection with the case.
The gang had allegedly waylaid Joginder Singh in Narela on September 1 after one of them posing as a policeman stopped his vehicle for checking. They robbed him of money after forcibly taking him to a building in a secluded place.
They also forcibly took photographs of him with a woman in a compromising position and later abandoned him on a road. He later approached the police.
A fortnight later, the gang demanded Rs four lakh from Singh threatening that they will make public his objectionable pictures if he does not pay.
"On September 15, a raiding party went to Auchandi Border with fake currency of Rs four lakh. At around 10:30 PM, an SUV approached the complainant and snatched the cash bag and fled. Another car was following the SUV.
"Both the vehicles were intercepted by police after a chase. Dahiya, Amit Pawan and the teenager were apprehended. Their interrogation led to the arrest of Lalita," Rizvi said.
