The labourers, who returned about a fortnight ago, alleged that they were lured on promises of hefty remuneration and free accommodtion by an agent of Parajaguda village in Borigumma block of the district.
"I was promised a monthly salary of Rs 4,000 and free accommodation. Though I worked for over a month, I was not paid a single rupee by the contractor. I was forced to work more than 10 hours a day," claimed Jogendra Jani (20), one of the labourers.
He said an agent had lured him and 14 others to Bangalore about two months ago. They had left their village on August 25 and taken to Balugaon in Khurda district. From there, another person took them to Bangalore.
"When the contractor refused to pay us and asked us to collect our wages from the agent, we left our workplace and reached our village with much difficulty," said Madhab Harijan, another labourer.
The labourers said after reaching their village on October 20, they approached the concerned officials to ensure that they get their wages.
"The matter is being examined thoroughly and all steps will be taken to ensure that the labourers get their wages," said assistant labour commissioner of Koraput S K Sahu.
Many people from this tribal dominated district go to work in Andhra Pradesh and Karnataka on being lured by agents, who promise them better wages.
