A Dubai expatriate was found dead at his in-laws' house at Rajabaria village in Nalchity upazila yesterday.
The deceased was Abu Sayeed Khan, 35, of Purbo Ranapasha in the upazila. He came to Bangladesh from Dubai two weeks ago.
Sayeed went to his in-laws' house at Rajabaria on Tuesday evening, said his elder brother Abu Taleb Khan.
In the morning, he was found dead, Taleb said, adding that he was informed over phone from the house that his brother died of disease.
Sayeed married Hamed Shikder's daughter Sonia Begum two years ago, said family sources.
They went to the house and found that the body bore some torture marks, said the victim's brother.
Whether it is suicide or murder will be confirmed after the autopsy, said Nalchity police.
