Photo courtesy of Vietnam News Agency Two Chinese tourists who robbed a petrol station in Quang Ninh should face criminal charges, provincial police have recommended. Ding Shi Jie, 30, and Ding Ning Shan, 36, entered Vietnam illegally on Tuesday through the Mong Cai border gate, the Vietnam News Agency reported. The same night, the duo broke into the office of a petrol station in Hoa Lac Ward in Mong Cai Town, around 156 kilometers (96 miles) northwest of the world-famous Ha Long Bay. When a female staff of the petrol station spotted the duo and raised an alarm, they gagged her and tied her hands before ransacking the office. They also took a cell phone and VND210,000 ($9) from the woman. Residents who heard the commotion alerted the local police. They also caught Shan and took him to the police station, while Jie escaped with a car at the petrol station. Jie was caught by the police when he tried to ram the car he was driving into the police vehicle in an attempt to rescue his accomplice. Cases of Chinese nationals illegally entering Vietnam via the border in Quang Ninh are common. In several instances, they have been caught overstaying their visas after a trip to Ha Long.
