Manipur Chief Minister O. Ibobi Singh Wednesday ordered a judicial probe into the incident, besides suspending six police officials.

Since July 15, movement of trucks on NH-39 and NH-53 has been stopped following strike by ATSUM demanding implementation of reservation policy for tribals and about 50 trucks loaded with various essential goods are now stranded at the Manipur-Nagaland border due to the strike.

Various transporter organisations, including All-Manipur Inter-State Bus Association (AMISBA) and the Manipur Drivers' Welfare Association, are on strike since Wednesday to demand security for truck drivers and improvement of the two national highways.

Movement of vehicles from Imphal to Moreh, the town on the border with Myanmar, has also been stopped.

As the trucks are not plying normally for about 22 days now, oil depots were not open even during curfew relaxation hours.

Prices of essential goods have shot up in IMphal and other parts of the state.
