Patna, Jan 19 (IANS): The 16-year-old son of a property dealer who was kidnapped for ransom on Thursday was found murdered here on Friday, police said.

The body of Raunak Kumar, a Class 9 student and son of Sudhir Kumar, was found in a shuttered shop in Kadamkuan locality. His hands were tied with a rope.

"Raunnak was kidnapped by motorcycle-borne criminals in broad daylight on Thursday morning when he was on way to his school," Patna's Senior Superintendent of Police Manu Maharaj said.

According to a relative, the kidnappers demanded a ransom of Rs 25 lakh from his father for the teenager's safe release. Sudhir Kumar received repeated phone calls from the abductors.

One of the kidnapper arrested on Friday revealed that the boy was killed after the father failed to cough up the money on time.

The opposition mounted fresh attacks on the government of Nitish Kumar over what they said was rising lawlessness in the state.

"Hardly a day passes without murder, kidnapping, extortion and robbery reported in the state but Nitish Kumar is more busy in his 'yatra'," RJD state President Ram Chander Purve said.
