But a CBI inquiry later proved the sabotage was planned and executed by some PCAPA
The irate villagers said that they torched the office in retaliation to the police highhandedness and as a protest against the arrest of their local PCAPA functionaries.
Zindabad (hail) our crusade against police highhandedness and we will protest till Joydeb Bera and Adak are released," said Sanatan Hansda, a PCAPA leader.
As the shutdown began, the PCAPA
activists set afire a pick-up van of the police near Jhargram town.
A Trinamool Congress activist, 24- year- old Bapi joined the PCAPA
when it was formed in November 2008.
He said it would be wrong for the CBI to link the PCAPA member with the Trinamool.
But CBI officials claimed that Bapi was present at Mamata's rally at Lalgarh in February 2009, where she also met PCAPA convener Chhatradhar Mahato.
The Jnaneswari Express incident -- PCAPA posters were found at the site of the carnage -- exposed the organisation's direct link with the Maoists.
Bapi was traced on Saturday after the CBI arrested another PCAPA member, Bholanath Mahto, from Khemasuli village near Jhargram.
Four more youth, suspected to be members of the PCAPA
, a Maoist front group, have been picked up for questioning.
