Superintendent of Police Nitul Gogoi said local people noticed that wires were sticking out of jars kept on the tracks and informed the police.
Bomb experts have taken away the jars and would examine them, Gogoi said. Northeast Frontier Railway Chief Public Relations Officer Subroto Lahiri said in Guwahati that train movement on the railway line was not affected by the recoveries.
Security measures have been intensified in the district, which has been witnessing protests against the upcoming Rabha Hasong Autonomous Council elections between November 13 and 25. The protesters were demanding that non-Rabha areas be excluded from the Council.
