Dinesh, who carries aliases like Chasma and Chhota Bikash, surrendered before Deputy Inspector General of Police Saket Kumar Singh and Latehar Superintendent of Police Anoop Birtheray.
In the presence of the police officers and the media, Dinesh said he had joined the Maoist outfit in 1996 following alleged police atrocities, exploitation of villagers and due to unemployment, but came back to the mainstream as socialism could not be established with armed revolution.
The DIG said the Maoists have got a jolt with the surrender of Dinesh, who was their backbone, entrusted with strengthening their organisation in the area.
Dinesh faces cases in Palamau (six), Latehar (six) and Lohardaga (11).
