Police also arrested ten workers from the spot.

Factory staff Altaf and Alamgir came under attack by a group of workers whom they had rebuked early in the morning for delay in joining work.

Following the incident, workers of the factory got divided into two groups and locked into clashes.

Several workers were injured and machinery vandalised during the incident.

The factory was declared closed for yesterday.

"An uneasy atmosphere was prevailing in the factory for the past few days. The arrests have been made to thwart any further violence," Officer-in-Charge of Ashulia Police Station Obaidur Rahman said.
