"He then slept beside the body and came to the police station on Friday morning to confess to his crime and surrender," the official informed.

He said Vinod Pawar was a borewell commission agent while Priyanka Rathod was a nurse at Tuljapur, adding that the couple had married nine months ago and the woman was five-month pregnant.

The woman's family told police that the accused used to demand money from her parents and this led to frequent quarrels, the official said.

A case of murder has been registered and further probe was underway, he added.
