The miscreants made the attack during a drive conducted at a sand quarry in Sherpur upazila by a team of mobile court led by the UNO.
Police said the UNO’s vehicle was damaged in the attack.
UNO Liyakat Ali said a team of mobile court conducted a drive in the area on information that some unscrupulous people were lifting sand illegally from Nabinagar and Naldangi areas under Khanpur union.
During the drive, the UNO said, he asked his team to seize the equipment used for lifting sand.
At one stage, Liyakat Ali said, some miscreants encircled them and beat up two of his team members and damaged the vehicle.
SM Abul Kalam Azad, officer-in-charge of Sherpur Police Station, said a team of police went to the spot and rescued the UNO and his team members.
