The arrest comes after the two high-profile arrests of Baazee.com CEO, Avnish Bajaj, and IIT Kharagpur student, Raviraj, in this connection.
The teenager was arrested late on Sunday evening from the Capital, although officials were tightlipped on the place from where he was picked up.
Sources said the boy had gone to Nepal and returned after arrests warrants were issued against him. He will now be interrogated to put together the chain of events leading to the circulation of the controversial clip, which was then sold on Baazee.com by Raviraj and also found its way to the market in the form of CDs.
Police sources said the boy is likely to be charged under Sections 292 and 294 of the IPC and Section 67 of the IT Act.
According to Delhi Police, the boy is central to the entire episode. Officials said he would be interrogated to ascertain whether the act was filmed with the intention to circulate it among others or even sell it. Police also hope that the boy would name those to whom he had sent the clip and if any money had exchanged hands.
Officials said all legal formalities had been followed in the arrest of the juvenile, who will be produced in court on Monday. The girl and the boy involved in the incident, both students of Delhi Public School, RK Puram, were suspended and later left the school.
The boy was also a member of the Delhi Under-17 cricket team this season but didnâ€™t play a match. He was part of the team from the second game against Himachal Pradesh at Una and also in the match against Haryana (at Gurgaon). He withdrew before the match against J&K (December 12-14) after the â€˜video clipâ€™ incident and opted out submitting a medical certificate citing ill-health.
