As many as 13 employers have been arrested and four establishments sealed during the raids led by Sub-Divisional Magistrate (Seelampur) Radha Charan in Ghonda in north-east Delhi, Bachpan Bachao Andolan said in a statement.
The rescued children in the 7-13 years age bracket were trafficked from remote villages of Uttar Pradesh and Bihar and were working in these factories for over a year, the NGO said.
Of the 26 children rescued, 19 were working in garment industries where they were involved in embroidery and stitching of cloth.
Seven children were rescued from metal polishing units where they were found to be working in extremely hazardous conditions.
“In this scorching summer, they were locked in small dark compartments to work with harmful acids and poisonous gases in a temperature as high as 43 degrees Celsius,” the statement said.
