Five masked Asian men armed with knives stormed into an Ajman apartment used by three Asian women as a massage centre and stole their money and mobile phones.
The three Asian women opened the door when the bell rang as they thought they were customers coming for a massage session.
The five then jumped on the women and pointed the knives in their faces before taking their money and mobile phones and fleeing.
Newspapers said police arrested one, who was sentenced by a criminal court on Tuesday to one year in prison and ordered deported from the UAE. The other four are still at large, they said.
