A Nepali migrant worker apparently died in his sleep here in South Korea, Nepali Embassy in Seoul confirmed.

Kalyan Rai, a native of Chiprai VDC-1 in Khotang district, who went to sleep on Thursday after work, was found dead the next day.

He was working at a thread factory in South Korea.  He was about to return home after working for four years and 10 months, said Khotang Service Society Korea Chairman Amrit Rai. He had also bought the ticket for May 13 to return Nepal.

Acting Nepali ambassador Kiran Shakya said local police has informed the Seoul-based Nepali Embassy about the death.

Two other Nepali workers had died in their sleep during the past one month.

Earlier on March 27, Tapin Katuwal, of Sunsari, and on April 10, Chudaraj Oli died in their sleep. The Nepali migrant workers are worried after the number of people dying in sleep increased recently.
