Cyber crime police of Cyberabad tracked down the 17-year- old boy to Surajpur district of Chhattisgarh.
On May 5, a 23-year-old city-based aspiring model had received alerts on her another email ID that there was a suspicious log-in at her Gmail, Facebook and iCloud accounts.
She could regain the access to these accounts, but two weeks later, she found that her private pictures and a video clip had been sent through WhatsApp from a stranger's number.
As she used the same user ID and password for Gmail and iCloud, he could hack them too.
The boy had been sent to a juvenile home twice earlier for similar offences targetting two models in Maharashtra, police said, adding that further probe is on.
