The victims are: Yar Ali and his wife Rozina Khatun. Their throats were slit, police said.
Quoting locals, Abdul Khalek, officer-in-charge of Damurhuda Police Station, said Yar and Rozina were last seen Saturday evening.
As nobody had seen then since Sunday morning, neighbours became worried.

They said Yar, who had two wives, had a feud with his second wife over property.
