Seven men and one woman were arrested and detained after officers visited businesses in Chelmsford and Maldon to check on the welfare and legal status of the people working there.

Chelmsford and Maldon Neighbourhood Policing Team were joined by officials from the immigration service, local council representatives and a victim navigator from the charity Justice and Care, following an investigation into modern slavery and organised immigration crime.

Arrests were made at three locations but there were no causes for concern at the majority of businesses visited.

The operation was led by Sergeant Matt Dalby. He said: "We were looking for evidence of organised immigration crime and to identify victims of modern-day slavery and forced labour, as well as suspects that may be responsible for facilitating that kind of criminality.

"One individual attempt to run from us but he was tracked down and caught. Those detained may initially be reluctant to tell us why they're at the premises but once they are spoken to away from that environment, they may disclose they are victims of exploitation.

"This is not an issue that many people who live in Chelmsford or Maldon may be aware of, but we have seen examples of people living and working in extremely poor conditions.

"This was an intelligence-led operation, and we will continue to ask the public to report to us whenever they have suspicions or are worried about the welfare of individuals they may encounter."

Bob Fortt, Prevent and Protect Officer for Modern Slavery and Human Trafficking added: "Exploitation is taking place in Essex. People get trafficked or smuggled into the country and forced to work for little or no money.

"There are signs - physically people may look malnourished, scared, agitated, avoid eye contact, perhaps have no English at all, and generally look unkempt.

Modern slavery can see victims exploited, controlled or held captive, and threatened or punished to stop them escaping. Those most at risk may have issues with money, social or health difficulties, or may be vulnerable because of their age or immigration status.

In Essex, there are anti-slavery partnerships in Chelmsford, Colchester and Southend where officers work alongside local councils, charities, the voluntary sector and faith groups to raise awareness, deliver training and support victims.
