"These child labourers were rescued in a joint raid by NGO Bachpan Bachao Andolan, Labour department, Delhi police, National Legal Services Authority and Delhi Legal Services Authority," police said.
Twenty-eight child labourers from Bihar, seven from UP and one from West Bengal were rescued, they said.
The children were allegedly forced to work in poorly lit and ill-ventilated rooms and had to stay there itself, according to police.
One of the rescued children said he had been working for past six months in a unit and was forced to work for 16-17 hours a day without any remuneration.
All the rescued children have been sent to an NGO under the orders of Child Welfare Committee and their repatriation formalities are underway, he said.
