请将下面这段话改写得更加正式、专业：

日前， cameras placed throughout the city showed a suspect attempting to steal a bike. The police traced the suspect to a pizza parlor. But, unfortunately, the suspect fled and couldn’t be caught. However, the police do have a clear picture of the suspect and the make and model of the stolen bike. We ask that if anyone recognizes the suspect or has additional knowledge of the bike's whereabouts, they should contact the authorities.

近日，全市范围内安置的摄像头捕捉到一名嫌疑人企图盗窃一辆自行车。警方根据线索追踪至一家比萨店，但遗憾的是，嫌疑人逃脱，未能将其擒获。不过，警方已掌握嫌疑人的清晰影像以及被盗自行车的品牌和型号。我们呼吁，如若有人能认出该嫌疑人或掌握有关自行车去向的其他信息，请及时与相关执法部门取得联系。
