More than 50 suspected migrants have been found in the back of two lorries in separate incidents in Kent.
Twenty-five people, including men, women and five children, were discovered in the back of a truck in Bridge Close, Dartford, on Monday.
Police said 26 others were found in a lorry in Coldharbour Lane, in Bridge, Canterbury, on Wednesday.
The arrested groups have now been handed to Home Office immigration officials.
They are from Iraq, Iran and Syria.
Officers said that following the Canterbury discovery, a 27-year-old man was arrested on suspicion of assisting illegal entry to the UK.
Those stowaways were found by workers at the Kent produce company, Gomez, who heard them shouting as they began to unload the truck at the depot in Bridge.
Owner Jim Parmenter said a woman and a young boy were among the migrants who came out of the vehicle.
"It's something we have to put up with as part of our operating life these days - either people in amongst the load on the truck, or quite often we see signs of contamination on the loads.
"If we know that people have been on the load that also has to be destroyed... that's about a £25,000 loss per lorry at least," he said.
Mr Parmenter added that his company had dealt with at least 15 similar incidents in the past year.
