Kolkata, June 24 (IANS) A pro-Maoist activist has been arrested in West Midnapore district for his alleged involvement in the sabotage that led to the Gyaneshwari Express train derailment in West Bengal last month killing 148 people, police said Thursday.

‘Amiya Mahato was nabbed last (Wednesday) night for his involvement in the sabotage,’ Jhargram Superintendent of Police Praveen Tripathi told IANS.

He is the seventh man to be arrested for the May 28 sabotage of rail tracks by suspected Maoists that caused the derailment of the Gyaneshwari Express. Several of the derailed train coaches which rolled on to a parallel track were then hit by an oncoming goods train.

Mahato, who was arrested from Koimasoli village, will be produced in the Jhargram court Thursday.
