Parag Mondol, the six-year-old boy kidnapped in Keraniganj on the capital's outskirts three days ago, was found at Atibazar in the locality early today.
The abductors had shot and injured the child's mother, sister and driver of their family before taking him away on Sunday morning.
"We got back Parag by the grace of the Creator," Parag's uncle Pradeep Kumar Dutta told The Daily Star at 12:35am.
He said they found him in front of Nupur Community Centre at Atibazar under Keraniganj Police Station around 12:15am.
Parag, a KG-1 student at Heed International School in Old Dhaka, was then rushed to the capital's Square Hospital since the abductors had hit him in the head with a pistol butt, said Pradeep.
Family sources said they got the child back for a hefty ransom while intelligence officials of the Rapid Action Battalion said the victim's family had paid the abductors Tk 50 lakh.
The money was handed over at a place a few kilometres from Aminbazar on the outskirts of the capital.
An armed gang of four had kidnapped Parag, son of businessman Bimol Chandra Mondol of Shuvadda Pashchim Para in Keraniganj. The criminals had also shot his mother Lipi Rani Mondol, elder sister Pinaki Mondol and their driver Nazrul Islam.
The four, riding on two motorbikes, intercepted Parag and his two sisters, mother and driver while they were about to get into their private car for going to school around 7:15am. The criminals sped away picking Parag on one of the bikes.
Lipi Mondol was admitted to the National Institute of Diseases of the Chest and Hospital at Mohakhali, Pinaki to Pongu Hospital and the driver to Mitford Hospital.
Some sources said the boy was dropped near Nupur Community Centre by the abductors' men.
Dipu Sarkar, 40, a relative of Parag's family, said, "A security guard of a local market told me that a child was found here. He also asked me to check whether the boy was my relative's son."
