Abu Dhabi Police have arrested four men on suspicion of printing more than 100,000 massage cards. Officers said they uncovered three printing houses that supplied the cards for distribution in Abu Dhabi city and Al Ain. Motorists often find these cards, bearing photos of women and advertising unlicensed massage services, placed on their vehicles. The cards are often found tucked under vehicle windscreen wipers and on door windows and handles. The four accused were identified by the police as Asian. No further details regarding the case were revealed.
