An employee of Hindustan Aeronautics Limited was killed in stone-pelting, allegedly by Maharashtra Navanirman Sena activists, who were protesting the arrest of their party chief Raj Thackeray in Nahsik today.

The victim, who was returning home from Ojhar, died after he was hit by stones on the company bus near Adgaon, police said.

The MNS activists also tried to set ablaze a Maharashtra State Road Transport Corporation bus at Deepali Nagar on the Mumbai-Agra national highway. A bus coming to Nashik from Mumbai was also stoned this evening and its driver was injured.

A couple of MSRTC buses were stoned at various places in the city after the arrest of Raj, police said, adding that 15 persons were injured in the violence.

Additional policemen have been deployed at Mumbai naka, Nashik Road railway station and other parts of the city as a precautionary measure.

Meanwhile, Maharashtra Navnirman Sena's Nashik unit president Nitin Bhosale was today arrested along with five other party workers, as over 40 incidents of stone pelting were reported soon after Raj Thackeray's arrest.

Although the police have taken adequate precautions, including rounding up of MNS workers, there is likelihood of a rise in such incidents as Nashik has a significant number of MNS supporters.
