Residents of CISF staff quarters at Indirapuram informed police about the foul smell emanating from constable Suresh Kumar Sharma's house, SSP Nitin Tiwari said.
Sharma (42) was found dead in the drawing room, whereas his wife Babli's (36) body was spotted in the bathroom, he said.
Prima facie it appears that the couple was strangled to death, the police official said.
They were married about 15 years back and did not have any children, Tiwari said, adding, the matter was being probed further.
