A woman died mysteriously at Sadar upazila in Panchagarh district on Wednesday morning.
Deceased Rokeya, 25, was the wife of Ershad Hossain, a resident of Jothasna village under Satmera union in the upazila.
The deceased's father Rabiul Islam said Ershad informed them at early hours of Wednesday over cell phone that Rokeya went out of the house and they could not find her.
The couple locked into an altercation in the night, Rabiul added.
Later, locals spotted the floating body of Rokeya in a pond at the village this morning.
Being informed, police recovered the body and sent it to Panchagarh Sadar Hospital morgue, said Panchagarh Sadar Police Station OC Abdul Latif Miah.
Police, however, detained Ershad for questioning.
The reason behind the death would be known once the autopsy is done, the OC added.
