Ashokan, 52, allegedly hanged himself on December 25 in a store room near his place of residence, his friends told the Times of Oman.
"Now, the necessary papers required to send his body back to India are lacking. We are trying to collect them but things are becoming complicated," they said.
Ashokan, who hails from Kerala, was working as a caretaker of a building in Al Khuwair region.
"Ashokan was a good person. We don't know the reason behind his suicide. It was his roommate who found Ashokan hanging. Later, the police was called and the body was taken away," his friends were quoted as saying.
