Bihar Labour Minister Vijay Kumar Sinha on Friday said that crimes have increased in the state and law and order is a challenge. He said this in reference to the murder of an 88-year-old retired Commissioner of Irrigation Department and his 70-year-old wife in Patna on Thursday.

Sinha, who is a senior Bharatiya Janata Party (BJP) leader, said that most of the crimes are now committed by youths. "Nature of crimes have changed, youths are behind them."
