The Gangmasters and Labour Abuse Authority (GLAA) and Metropolitan Police have arrested two Indian nationals at a recycling plant in Barking on suspected immigration offences.
The raid was undertaken as part of a ’week of action’ into potential labour exploitation in London.
A GLAA spokesperson said the matter had been handed to the UK Border Police, and there was no suggestion that modern day slavery was taking place at the facility.
The name of the facility has not been released.
GLAA head of UK operations Ian Waterfield said: “While we have discovered some serious issues and laid the foundations for some solid working practices with key partner agencies, we know we have barely started to scratch the surface of the exploitation that exists in our capital.
“As an intelligence-led organisation, we need the public to provide us with information about labour abuse, financial and physical exploitation and possible modern slavery offences.
“We can and we will investigate but we can’t without help from the public.”
