Three days into the barbaric incident, police are yet to recover the severed leg of Kala Mia, a resident of Ruposdi village in Bancharampur upazila.
On Friday, Abul Bashar, vice president of Bancharampur upazila unit of Swechchhasebok League, and his men allegedly severed the right leg of Kala Mia, 45, from the knee over previous enmity and took it away.
They also cut tendons of both the legs of Kala Mia’s son Biplob Mia, 20, during the time.
The injured are now undergoing treatment at Dhaka Medical College Hospital, said police.
Salma Akter, wife of Kala Mia, on Sunday filed a case with Bancharampur Model Police Station against 15 people including Abul Bashar, also a sand trader.
Salma said they are passing their days in panic as police are yet to arrest Bashar Mia.
Meanwhile, Bancharampur upazila unit Swechchhasebok League in an emergency meeting on Sunday night expelled Abul Bashar from the party for his involvement in the heinous act, said Lokman Hossain, president of the district unit of Swechchhasebok League.
Two months ago, Bashar and his cohorts torched the house of Kala Mia following an altercation over sand trading. As the victim filed a case with a court against Bashar in this regard, the accused carried out such acts of barbarism.
Additional Superintendent of Police Alamgir Hossain said they are raiding different areas to arrest the accused.
