The dead Abdullah was son of Sohag Hawladar, a resident of district's Nishanbaria area.
Police arrested Hridoy Chaprashi, the prime accused in a case filed in this connection, from the capital's Sayedabad area on early Saturday. They conducted a drive, taking Hridoy along with them, yesterday morning to recover the body, said Riazul Islam, additional superintendent of police in Morrelganj.
Riazul said Hridoy, along with his cohorts, abducted the child on early March 11 by penetrating their house through a window.
