''I have sought for a thorough investigation to find out if some policemen were aiding the GNLA militants in last week ambush against five security personnel,'' Mr Lyngdoh told reporters.
Three policemen were killed and two others were injured in an ambush laid by the GNLA militants at Thapa Darenchi in state’s East Garo Hills district.
Admitting that there are ''black sheep'' in the police department, the Home Minister warned action against any police personnel if found aiding and abetting the militant groups.
A number of police officials in Meghalaya have come under the scanner of central intelligence agencies for their alleged links with the GNLA, led by a trained deputy superintendent of police-turned rogue Champion R Sangma.
'' Two police inspectors, four sub inspectors and a good number of constables based in Garo Hills region are under the security scanner for their linkages with the GNLA,'' a top MHA official told UNI.
According to the official, these police personnel were believe to have passed strategic information to the GNLA ahead of any operations against the militants.
