Hundreds of arrests have been made across the UK as part of a "week-long crackdown" on asylum seekers taking jobs for delivery firms.
A total of 1,780 people were stopped and spoken to over suspected illegal working activity between 20 and 27 July.
Some 280 were arrested as a result - in areas including Hillingdon in northwest London, Dumfries in Scotland, and Birmingham.
Some 89 of those have been detained pending removal from the country and 53 are now having their asylum support reviewed, which the government said could result in their support being suspended or withdrawn.
