Around 100 workers of Haesong Corporation Limited in Uttara vandalised the administrative, commercial and inspection rooms on the first floor of the factory demanding immediate measures to punish the attackers.

The authorities said they tried to calm down the workers by assuring them of taking steps against the culprits through the law enforcers, but some angry workers did not pay any heed to them.

The agitating workers broke some windowpanes and doors with iron rods at about 8:15am to enter the office rooms to beat the officials, but other colleagues restrained them until police took control of the situation, they claimed.

The workers said they do not have any problem regarding their 22-point demand that they made during the unrest in last month as the Korean authorities are meeting most of them.

But the four staffs who were fired for their misbehaviour with the workers made the attacks to get their jobs back, they added.

The sacked are Production Manager Kamrul Islam, General Manager Khalek and Supervisors Anwar and Rafiq.

The workers said the authorities have nexus with the sacked officials to bring them back as no appointment has been made in any of the vacant posts.

Nazim Uddin, personal manager of the factory, however denied the allegation saying that the four were fired on June 7 and they have no chance to get back their jobs.

"Yesterday's (Sunday) attack was merely an incident occurred outside the factory," he added.

Police have been deployed to avoid any untoward incident and the officer-in-charge sat in a meeting with the workers and authorities to settle the issue.
