This was an excellent piece of work by all officers involved. Not only did they arrest an individual who was in the UK illegally, but they also prevented a quantity of Class B drugs making it onto our streets.
This was the latest in a series of operation tareting illegal immigration in Sussex, and for those who are living and working here illegally there is no hiding place.

But Sir Roger Gale, the MP for Thanet North says it's an 'outrageous' situation and is urging the Home Secretary to take action.
