A man who had sent multiple death threats to Delhi Chief Minister Arvind Kejriwal over email in a bid to draw public attention, has been arrested, Delhi Police said on Friday.

The arrested man, identified as Abhishek Tiwari, 28, belongs to Uttar Pradesh’s Unnao but was living in Mumbai’s Nala Sopara since 2016. In a series of tweets DCP Cyber Crime said, “A school dropout, he was not satisfied with his job and his life, and wanted to do something big to draw the attention of people. He came up with the idea of sending threat emails to political leaders.”

Deputy Commissioner of Police, Cyber Crime Unit, Anyesh Roy said that they had received a complaint last month from Delhi CM’s office about getting life threats to Arvind Kejriwal over email and had launched an enquiry.

During investigation, based on technical analysis of inputs collected regarding origin of e-mail, connected mobile phone and IP logs, teams were rushed to Mumbai and Kanpur for locating the suspected user of the relevant email id, police said.

“The suspect, however, had gone underground and was leaving very few digital footprints. With deep analysis of technical inputs, his location was zeroed to Nala Sopara, Mumbai, a densely populated area. The team in Mumbai searched through hundreds of chawls till the accused was finally nabbed,” Roy said.

In its tweet DCP Cybercrime mentioned, the accused had also sent an email to a municipal office bearer of a major political party in Mumbai, but “disappointed with the lukewarm response, upped the ante and decided to send threat mails to senior political leaders.”

Tiwari is being interrogated and the mobile phone he used to send the emails has been recovered for cyber forensic analysis, a senior police officer said.
