The two accused were arrested on November 9 from Sarai Kale Khan bus stand.
Two persons have been arrested for allegedly holding a Gujarat-based businessman captive after calling him to Delhi to buy an old vehicle at low price, police said on Friday.
The two accused, identified as Javed and Mosam, were arrested on November 9 from Sarai Kale Khan bus stand, joint commissioner of police (crime) Ravindra Yadav said, adding that two of their accomplices were nabbed in August.
"They used to give advertisements in newspapers in far flung areas of Maharashtra and Gujarat for sale of vehicles, especially cars and scrap materials, at throwaway prices. People used to fall prey to such advertisements and get trapped in their net," he said.
Valji Bhai, a Bhuj-based businessman reached Delhi on December 21 last year after he received calls from persons offering to arrange a car for him at low price, said Mr Yadav.
After arriving in Delhi, he met a person at the railway station, who took him to Palwal on the pretext of showing him the car.
"On reaching Palwal, he noticed that there were more persons who were already present there. He was forcefully taken to a secluded place. They demanded a ransom of Rs 5 lakh from his son. The accused also took Rs 20,000 that he was carrying and his mobile phone," said the officer.
When there was an alarm about a police raid being conducted in the area, the kidnappers fled leaving behind the businessman, he said.
"A specific information was received and two accused, Taufiq and Sunny, were arrested by the Crime Branch on August 23," Mr Yadav said.
During investigation, involvement of five more criminals -- Mosam, Javed, Sajid, Hussain and Saddam -- came to the fore and efforts were made to arrest these criminals, he said.
After police received an input that Mosam and Javed would be coming from Rajasthan to Delhi to meet their associates, a trap was laid and they were nabbed from Sarai Kale Khan bus terminus, the officer said.
