A group of armed Maoists abducted seven labourers in Bihar's Jamui district, police said Friday.
The labourers, engaged in lifting sand from a river bed, were kidnapped from near Navinagar village, about 200 km from here.
Superintendent of Police Jitendra Rana said: "A team of security forces, including the CRPF, is on work to rescue them."
Rana said the Maoists also torched two poclain machines engaged in digging and lifting sand from the river bed.
Police suspect the workers were abducted because they refused to pay the levy demanded by the Maoists.
Jamui is considered a Maoist stronghold.
