Two men and a woman have been arrested on suspicion of trying to sell stolen gold to a jeweller in the central gold souq in Sharjah.
The shopkeeper contacted police after they could not produce receipts.
When officers approached them they ran away but were soon caught.
The woman, from Ethiopia, admitted stealing the gold from a family for whom she had been working since absconding from her sponsor.
The men, from Cameroon, and the woman, who were all in the country illegally, have been referred to the Public Prosecution.
