Indian authorities have arrested and charged with murder 60 dismissed workers of a car part plant outside New Delhi for bludgeoning to death their employer on Monday.

Those arrested were among the 125 former workers who barged into the factory in Greater Noida and beat Lalit Kishore Choudhary, head of Graziano Transmissioni India, with sticks and iron rods after he tried to pacified them. Police said the 47-year-old victim suffered severe blows in the head and bled to death.

Choudhary apparently invited the workers to discuss their reinstatement. He talked with a few of them inside his office before others outside went into a rampage and attacked the factory. He had fired the workers in recent months for being involved in violence inside the factory.

Other executives inside the plant were not harmed when they locked the doors of their offices until the police arrived. Two other people were injured in the riot and hospitalized.
