Abducted from outside his East Delhi house in 2010, Sonu has now been handed over to the Indian High Commission in Dhaka by a court in Bangladesh's Barguna district and will be reunited with his family after a gap of six years.
Barguna Additional District Judge Abu Taher granted Sonu's custody to Indian High Commission officials on Monday without signing of a security bond of one lakh taka (Bangladesh currency) on humanitarian grounds.
Sonu, who was tricked and brought to Bangladesh from Delhi by two women in 2010, was rescued by a Bangladeshi citizen Jamal Ibn Musa, who put in great efforts to reunite him with his family.
"I am very happy. Finally, Sonu is getting reunited with his parents," the Daily Star quoted Musa as saying.
India's External Affairs Minister Sushma Swaraj, in a series of tweets, thanked all who had looked after the young boy in Bangladesh.
"Sonu - who was kidnapped from Delhi was found in a shelter home in Bangladesh. We matched the DNA with his mother. The test is positive," Swaraj tweeted.
"Indian High Commission in Dhaka has obtained Sonu's custody. He will reach Delhi on 30th June. I thank all those who looked after our young citizen in Bangladesh," she said.
