Ten activists of Awami League were injured in a clash between two factions of the party at Samair in Savar on Monday.
Locals said Sajib, a local AL activist, had an altercation with some other party men over wearing the 'Boat' badge on the election day on Sunday.
As a sequel of the incident, a group of AL men swooped on the house of Sajib in the morning.
On information, the associates of Sajib also went to the spot and retaliated, triggering a clash.
A chase and counter-chase took place between the two groups that left 10 people injured.
The injured were taken to a local hospital.
Abdul Awal, officer-in-charge of Savar Police Station, said a case was filed in this connection.
