New Delhi, Feb 21 (IANS): A 23-year-old jilted lover, described as an "over-smart engineer", has been arrested from here for allegedly harassing and sending obscene messages to a Delhi University student.

The accused, Aman Singh, a resident of west Delhi's Paschim Vihar area, made the best of his technological skills to create multiple fake accounts to send messages and make calls to the victim from fake international numbers using various mobile applications, Deputy Commissioner of Police Vijay Kumar said.

"The over-smart engineer displayed his all technical skills to mislead police, but Cyber Crime Cell succeeded" in tracking him down from his residence on Monday night, Kumar said.

Singh, who was working with a reputed IT-company and drew a "good package" in salary, had befriended the victim during a college fest in 2015 where they became friends but broke up after a couple of months, according to Kumar.

The police officer said Singh was unable to come up with the terms and started harassing the girl in social media networking sites, including Facebook and WhatsApp. The victim did not respond to his messages.

In frustration, the accused started sending "unwarranted messages" to her family members.

"He also threatened them. He created a fake account of the victim on 'Facebook' and sent friend requests to her friends and family members with obscene comments," Kumar said.

During investigation, police found that the accused used a Jio SIM of his college friend to send messages as an unknown person.

Kumar said the accused confessed the crime. Police have seized his mobile phones, laptops and other gadgets that he used to send messages.
