Shillong, Feb. 2: The Opposition United Democratic Party (UDP) today demanded a CBI inquiry into yesterday's incident at Umling in Meghalaya's Ri Bhoi district.

Yesterday afternoon, hundreds of alleged coal truck drivers and helpers who were allegedly armed with iron rods, petrol bombs, stones and canes, attacked the Umling weighbridge, few kilometres away from Nongpoh, the district headquarters of Ri Bhoi.

The armed men allegedly attacked the weighbridge counter and the offices of the directorate of mineral resources, sales tax and transport. The attackers were allegedly running out of patience as many of the trucks had been waiting to be weighed for the past five days. Sources said after vandalising the installations, the truckers fled from the area along with the unweighed vehicles.

An official source informed that a weighbridge would be made operational at Umling by tomorrow evening. Yesterday, the weighing machine at the weighbridge was damaged.

'The UDP demands a CBI inquiry into the incident at Umling to bring to light all discrepancies that had prevailed, which led to the much unwanted incident,' UDP general secretary Allantry F. Dkhar said.

'The government departments responsible for this mess needs to allot responsibilities and appropriate action needs to be taken for any lapse of duty,' Dkhar said.
