In July 2009, the German federal police stumbled upon some pornographic material featuring children on two popular net-availed software programmes, eMule and uTorrent.
This was the same time that Lieutenant Colonel Jagmohan Balbir Singh (42) had allegedly begun uploading his collection of child pornography on the net using the same software.
Sources in the Cyber Crime Investigation Cell of the Mumbai crime branch, which arrested Singh on Friday, told HT that Singh continued to upload and download child pornography until September 2009.
In December 2009, the German police traced the Internet Protocol address of the culprit. They sent a request through the Interpol to nab the suspect. The crime branch was alerted in February 2010.
Cyber crime officers traced the computer to Singh’s flat in Colaba. “We realised it belonged to a senior army officer and hence decided to work it out carefully,” Joint Commissioner of Police (Crime) Himanshu Roy said. The police watched Singh for more than two months to make sure he was their suspect.
The police got a nod from the Army before swooping down on Singh’s house on Thursday.
