The officials of the embassy traced Rana over the next three days and informed his family members, who later communicated with Rana's employer in Oman.

Averda, a waste management company in Oman, had been his employer, Monju Ara said.

In April 2018, Rana was brought back to Bangladesh.

"We stayed a month at Dhaka Medical College Hospital for his treatment after his arrival. But we decided to bring him back home as there was no sign of improvement," Monju Ara said.

The company said it would give Tk 31 lakh as compensation to my son, but the money has not been paid yet.

"Every week, we have to spend Tk 1,500 for his medicine alone, and he needs to be taken to hospital once a month," said the mother.

The expenses are beyond the ability of the family to bear, since it is already burdened with financial difficulties.

She urged the government to help the family secure compensation from Rana's employer in Oman. "If we get the compensation, we can at least take our son to India for better treatment," said Alam Hossain.
