A
The police are looking for robbers who stole valuable diamonds from the jewelry show at the City Centre yesterday evening. The owner reported that a necklace was taken by a young couple. It was worth 1.5 million. Witnesses said that a couple caught their eye because they seemed too young to be interested in such expensive jewelry. In his story, a salesman said that the couple were dressed in clothing that seemed too casual for the jewelry show. According to a saleswoman who talked with them, the couple said that they were interested in a special necklace for the woman to wear at their wedding next month. The man said that he was a well-known sportsman, so many reporters would come to the wedding ceremony.
The saleswoman left the couple looking at the necklace when she went to help an elderly man who fell out of his wheelchair. Unfortunately, when she got back, the couple and the necklace were gone. The police have realized that the old man was part of the robbery plan.
The police think the same gang of thieves robbed a hotel downtown last month. At that time, a woman was checking in when two men with guns threatened the hotel clerk. Although the clerk was very brave, he had to hand over all the money, about 1,500. Strangely, the woman who was checking in didn't seem afraid at all and she disappeared before the police arrived. The police are working hard to find the criminals.

警方正在搜寻昨天晚上从市中心珠宝展上偷走贵重钻石的劫匪。店主报告说，一条项链被一对年轻夫妇偷走了。它价值150万。目击者说，一对夫妇引起了他们的注意，因为他们看起来太年轻了，不应该对这么昂贵的珠宝感兴趣。一位售货员在他的描述中说，这对夫妇的穿着看起来对于珠宝展来说太随意了。据一位与他们交谈过的女售货员说，这对夫妇说他们对一条特别的项链感兴趣，想让这位女士在他们下个月的婚礼上佩戴。这名男子说他是一位知名运动员，所以会有很多记者来参加婚礼。
