Davangere, Jul 19 (IANS): A 9-year-old sniffer dog ran 12 km in the night to trace a murder accused and helped the police arrest him in Karnataka's Davangere rural area, an official said on Sunday.

"Doberman Pincher Tunga ran 12 km non-stop from the crime spot at Basavapattana in the city to a house at Kashipur in the rural where murder accused Chethan, 25, was hiding and helped us arrest him on July 17," Davangere Police Superintendent Hanumantha Rai told IANS on phone.

Davangere is 260 km northwest of Bengaluru.

"Though Chethan allegedly shot dead his friend Chandra Nayak with a stolen service revolver on July 10 over sharing the booty (gold ornaments) of the theft they had committed recently with two others. We took female dog Tunga to the crime spot on July 16. She led the sleuths to the area where Chethan was hiding with two accomplices," Rai recalled.

While trained sniffer dogs normally run 4-5 km from a crime spot, Tunga could track the accused 12 km away.

When Tunga's handler (Head Constable Prakash) took her to the crime scene at 9.30 pm, she sniffed around and ran 12 km non-stop to Kashipur. She halted at a wine shop and went to a food joint later. Then she stopped at a house nearby at 12.30 am.

The prime accused (Chethan) was present in the house of his relative. He was arrested after he confessed to the theft and the murder.

The police are on the hunt to trace Chethan's two accomplices who fled from the house they were hiding in.

Karnataka Additional Director General of Police (law and order) Amar Kumar Pandey felicitated Tunga on July 17 at a function here for cracking the murder case with its exceptional sniffing traits.
