Patna, Dec 24 (IANS): Hundreds of businessmen and traders took out a candle march in Bihar's capital on Monday to protest the killing of a young businessman. Bihar Opposition leader Tejashwi Yadav also joined the march.

Protesting businessmen and traders shouted slogans and demanded arrest of criminals behind the killing.

Gunjan Khemka, an industrialist, was shot dead last Thursday in Hajipur in Vaishali district, leading to panic among businessmen and traders of the area.

Khemka, son of Patna's well-known businessman Gopal Khemka, was targeted on way to his factory in Hajipur, about 30km from Patna.

Police are yet to make any breakthrough. Twenty-four hours after Khemka's killing, four businessmen, including a construction firm owner, were shot dead in the state.

Opposition Rashtriya Janata Dal and Congress leaders have criticised Chief Minister Nitish Kumar for the rise in crime and collapse of law and order.

Besides Tejashwi Yadav, senior Congress leader Tarique Anwar and Rashtriya Lok Samata Party chief and former Union minister Upendra Kushwaha have questioned Nitish Kumar's claims on improvement in law and order in the state.
