According to the complaint of Man Singh, brother of deceased Mohan, the woman's father Bhuri Singh called Mohan, who was working as a tailor under him, to his house last night and killed him with a sharp-edged weapon.

The bodies have been sent for postmortem, the SP said.
Man also alleged that Bhuri had taken a loan of Rs two lakh from his younger brother, he said.
