Dumka:
A Maoist, who is on bail, was arrested from Pokharia village in Dumka district in connection with the fatal attack on Pakur Superintendent of Police Amarjit Balihar and others at Kathikund on July 2.
"Satan Besra has confessed after his arrest on Sunday to have been involved in the attack on the SP convoy. He whistled to alert the Maoists when the cars approached," Deputy Inspector General of Police (Dumka range) Priya Dubey told reporters.
Mr Dubey said Besra revealed that the action squad from Giridih district of Jharkhand had perpetrated the crime.
The plot was set on July 1 and the Maoists attacked the police officer the following day, killing him and five other policemen, the DIG said.
Besra was on bail since January last year after he was arrested in connection with a Maoist-related violence, Mr Dubey said.
