Police on Sunday identified the body, which was lying inside a water tank in Adityapur on Saturday, as that of Raja Kumar (22), a third year student of Mechanical Engineering branch of NIT Jamshedpur.

RIT Police Station OC Rajesh Kumar Bhokta said the body was identified from the I-card of the deceased.

The resident of Gauspur block in Saharsa district of Bihar was missing from a hotel on Kalimati Road in Golmuri area of the city since February 14 night, and a missing person report was lodged by his father Roshan Kumar on February 19.

Raja was supposed to appear in a terminal exam on February 14, but he did not go to the college and instead stayed in the hotel along with a friend. After he went missing from the hotel, his friend had immediately informed his parents, leading Roshan Kumar to lodge the missing person report.

"Though the body was identified from the I-card of the deceased, we also summoned his parents to see the body, who confirmed it to be of Raja," Bhokta told The Telegraph Online.

He added they shifted the body to MGM Medical College for autopsy as he had already been registered with Golmuri Police Station in connection to this matter.

Golmuri Police Station OC Arvind Kumar said they had lodged a case of abduction when Raja’s father had filed the complaint, and will proceed accordingly.

"Let the autopsy report come. Then only we will determine whether it is a case of suicide or something else, " said Kumar while talking to this website.

According to sources of Raja's family and friend circle, the deceased's mental condition was not well and was very nervous when he came to Jamshedpur for his examination a week ago.

His body was recovered by a 25- memberteam of the NDRF late on Saturday night, after hours-long operation.
