Manjit Singh, who was working on merchant vessel Gulf Dove, is believed to be a victim of injuries sustained in a bomb blast in Yemen.
"Though he was admitted in a hospital, he was declared dead subsequently," defence sources said.
Indian Navy's stealth frigate INS Tarkash, which today evacuated about 450 people from Aden harbour, is carrying his body to Djibouti.
The exact dates of his injury and death was not immediately known.
India had yesterday wrapped up its air evacuation operations from Yemen rescuing another 630 of its citizens from Sanaa, taking the total number of Indians brought home from the war-ravaged country to over 4,640 besides around 960 nationals from 41 countries.
