Udayan Das, who had murdered his live-in partner Akansha Sharma and buried the body in a marble-top tomb at his house in Bhopal three years ago, was sentenced to life imprisonment by a first track court in Bankura on Wednesday.

Public prosecutor Arun Kumar Chatterjee said the judgment was pronounced on Wednesday but the court had convicted Udayan on Tuesday under Sections 302 and 201 of the IPC for murdering Akansha, 28, in 2017.

While he was being whisked away by police after the verdict, Udayan told news persons that he would move the high court against the judgment.

Bankura girl Akansha, who was the daughter of the manager of a nationalised bank, had befriended Udayan, who lived in Bhopal, through a social media platform in 2016.

Akansha went to Udayan’s home in Bhopal, but told her parents that she was in the US.

It later emerged that Udayan had killed his parents following a tiff over his career in 2012 at Raipur in Chhattisgarh. Sources said three separate cases were pending against Udayan at a court in Raipur.
