Kolkata, Nov 29 (IANS): Adopted by a Swedish couple 33 years ago, Swedish national of Indian origin Rebecca Aditi Sandlert is on a unique quest in India - to find her biological parents in northern West Bengal's Siliguri.

Born in Siliguri in 1980 to a Nepali mother and Bengali father, 34-year-old Sandlert was adopted in 1981 from an orphanage in Kolkata after her estranged parents abandoned her.

"I have come here from Sweden to look for my birth parents. I am looking for more information on my background.

"I know my mother was a Nepali and my father was Bengali. I don't know much about my background because I was adopted from here," Sandlert told a TV channel.

Sandlert grew up in Stockholm and became a social worker at the Stockholm Public Service. She is married to a Swede and has a one-year-old daughter.

On her first visit to India, Sandlert is being assisted by Bapan Das, a Kolkata Police officer, who shot into the limelight after helping a Bihar youth, lost in Siliguri, reunite with his family.
