The body of a 22-year-old engineering student, who went missing on Sunday, was fished out of a pond near his house in Baranagar on the city’s northern outskirts on Monday.

Police said Saurav Sengupta, a student of a private engineering college in Sodepur, had gone out pandal-hopping with friends on Navami night. His mobile phone was found on the steps leading to the pond in the locality. His gold necklace is missing, the police said.

Sengupta’s family members have said he didn’t know how to swim and had never taken a dip in the pond. He has been murdered, the family has said.

The family will file a police complaint after receiving the post-mortem report.

Cops will question the friends with whom Sengupta had gone pandal-hopping on Navami night, the police said. A few of them have told investigators that they had dropped him off near his house around 1.30am on Monday after visiting pandals in north Calcutta.

“Some of his friends told us that they were not aware of what happened to him after they had dropped him off near his house,” an officer of Baranagar police station said. “We are waiting for the post-mortem report to find the exact cause of death.”

Sengupta is the youngest child of Anirudhha and Sanchita Sengupta of Bhattacharjee para in Baranagar.

On the night of Navami when he didn’t return, his parents called on his phone only to find it switched off, the police said.

The next morning a resident of the area spotted a phone on the steps leading to the pond and alerted the family. The police were alerted and divers brought in. They fished out the body from the pond, the police said.
