Earlier, on Wednesday, miscreants severed the wrists of Romel Hossain, 28, at Ujirpur in Shibganj upazila.
Abdus Salam, uncle of the victim and a local Awami League leader, said Romel and UP chairman Foyez had been at loggerheads for long over establishing supremacy in a ferry ghat of the area.
Family sources said when Romel along with his two friends was returning home several people waylaid him near Ujirpur Beribadh and asked him to meet Ujirpur UP chairman Foyez.
As he went to the chairman’s office his hired goons blindfolded him and severed his wrists of both hands and left him near Beribadh area, they alleged.
On information, family members rescued him and took him to Chapainawabganj Sadar Hospital.
Two other people identified as Alauddin and Jahangir were arrested in this connection on Thursday.
