Four illegal immigrants snuck into England by hiding inside a 32-foot artificial Christmas tree, U.K. authorities said.

The fake tree, along with two smaller trees, were headed for the town of Northampton's holiday display, The Daily Mail reported Tuesday.

Delivery men discovered the four men, two from Iraq and two from Iran, inside the Christmas tree vehicle and called 911.

The immigrants were arrested and are currently being questioned by the U.K. Border Agency, The Mail reported.

"Following their arrest after being found in a lorry, four suspected illegal immigrants were apprehended and transferred to our specialist teams of officers," an agency spokesman was quoted in The Mail.

The driver of the vehicle carrying the three is not thought to have known the men were aboard.
