An immigration raid has led to the arrest of 13 people.
The incident took place at a warehouse in Shoreham on November 25, with 11 Brazilian and Romanian nationals detained for removal from the UK.
It comes as part of a wider crackdown on illegal working across the country.
Eddy Montgomery, director for enforcement teams at the Home Office, said: "While this is a great achievement, our activity won’t stop here.
"We will continue to bear down on this criminality in our towns, cities and villages to ensure there is no hiding place from immigration laws."
The raid forms part of a national surge in immigration enforcement activity, with 12,791 visits conducted in 2025 - up 57 per cent from 8,122 the year before.
Arrests also reached a record high, rising to 8,971 in 2025, nearly 59 per cent higher than the 5,647 recorded in 2024.
Of those arrested, 1,087 have so far been removed from the UK.
Immigration enforcement was given £5 million to arrest, detain and remove migrants working illegally at sites such as takeaways, beauty salons and car washes.
Body-worn cameras have been in use by officers since September to support arrests and prosecutions.
Home Secretary Shabana Mahmood said: "There is no place for illegal working in our communities.
"That is why we have surged enforcement activity to the highest level in British history so illegal migrants in the black economy have nowhere to hide.
"I will stop at nothing to restore order and control to our borders."
Since the Labour government came to power, visits have increased by 77 per cent and arrests by 83 per cent, according to the Home Office.
In total, 17,483 visits and 12,322 arrests were recorded between July 2024 and December 2025, compared with 9,894 and 6,725 in the previous 18-month period.
The government’s new Border Security, Asylum and Immigration Act has also tightened right-to-work checks.
Employers who fail to carry out proper checks could face up to five years in prison.
They could also face fines of up to £60,000 per illegal worker and the risk of having their business shut down.
