Interviews follow raid on VK Garment factory, the subject of a UK lawsuit against the supermarket from 130 ex-workers
Thai police and civil servants have begun screening more than 100 former workers at a factory that supplied Tesco to determine if they were victims of forced labour.
The Guardian revealed last week that Burmese workers who produced F&F jeans for Tesco in Thailand had reported being trapped in their work, enduring 99-hour weeks for illegally low pay in appalling conditions.
