"P.K. Boro, a block development officer (BDO) posted at Dadengiri and two traders, Rockybul Haq and Dulal, were abducted by GNLA rebels this afternoon," state police chief N. Ramachandran told IANS.
Ramachandran said Boro was abducted at gunpoint from his official chamber at Dadengiri block while the two traders were kidnapped from Kalchengpara weekly market.
"We are still investigating whether any ransom has been demanded," Ramachandran added.
The GNLA, headed by police officer-turned outlaw Champion R. Sangma, has unleashed a reign of terror in the three impoverished districts of Garo Hills in the western part of Meghalaya.
Over 20 people, including security personnel, have been killed in the area in the last one year by GNLA rebels.
Champion, who claims to be fighting for a separate Garoland, has been camping in Bangladesh for several months in search of support.
The outfit has also forged an alliance with the Bangladesh-based rebel group, A'chik Special Dragon Party.
Meghalaya shares a 443-km border with Bangladesh, part of which is porous, hilly and unfenced and prone to infiltration.
