Sunny Sharma, a net-savvy English medium student, reportedly had experienced similar kind of "excitement" earlier. Sharma reportedly sent a prank mail to BCCI to replace MS Dhoni with Parthiv Patil as the captain of India Cricket team.
The NIA team arrested Sharma from Pakur, a place near the Bengal-Jharkhand border. Sharma was booked under section 66(A) of the IT Act that deals with prank calls/mails that create panic among the public.
Multiple terror emails have so far confused the investigating agency NIA. They have received four mails claiming responsibility of the blast in which 13 people died and more than 70 were injured. Sharma reportedly sent the second and fourth mail.
