year-old Filipino is being held in the United Arab Emirates (UAE) for the killing of his Filipina girlfriend in Dubai one month ago. UAE news site Khaleej Times reported Wednesday that the Filipino confessed to killing the woman, with whom he had an affair for three years. The incident occurred in the Al Twar area of Dubai, prompting police to question some 421 Asians in a span of one month to get to the suspect. But Dubai police, with help from the victim's relatives in the Philippines, managed to identify and track down the suspect. Investigation showed the Filipino killed the woman after they had a fight in a parking lot of a residential area, with the man losing his temper when the woman threw sand in his face. The man held her by her neck and pushed her into his car. He returned to the car after washing his face. When the woman continued to argue with the man, he caught her again by the neck and strangled her with his belt. The woman lost consciousness and the man headed straight to his friends' home. Not finding anyone there, he fled, leaving the unconscious Filipina on the doorstep. Acting on information regarding a body in Villa No. 1 in Al Twar, police rounded up 421 Asian expatriates in the locality and interrogated them. One of them identified the victim and showed the police her flat. Sometime later, a police official patrolling the area saw the suspect getting out of the flat carrying a bag. The police apprehended him and found the victim's clothes in the bag. The police also learned the woman had run away from her sponsor in 2007 but the sponsor had not informed the police.
