Berhampur: A total of 78 people have been arrested for allegedly vandalising an industrial unit in Ganjam district and also assaulting cops, police said on Wednesday.

Police said that most of the accused, who were arrested on Tuesday night, are workers of the ferro chrome unit in the plant.

They were displaced during construction of the factory near Chamakhandi and were agitating for permanent jobs, a police officer said.

"Most of the agitators have been arrested for damaging plant properties after forcibly entering its premises on June 27. They had also attacked fellow workers," Utkal Keshari Das, Sub Divisional Police Officer (SDPO), Chhatrapur, said.

The agitators have also lodged a case against the cops accusing them of harassment, which is being investigated, a police officer said.

Meanwhile, parents of the arrested persons have threatened to stage a demonstration and prevent employees from entering the plant.

"We are keeping a close watch on the situation.
