Police in Henan have arrested eight suspects in connection with the robbery of an Amway retail store in Zhengzhou. After a nine-day, cross-province manhunt, Zhengzhou police and other local law enforcement agencies said they had arrested eight suspects they allege carried out the January 26 robbery, Henan's City Morning Post reported yesterday. According to reports, three masked men had stormed into the store and threatened to blow it up with explosives before escaping with 910,000 yuan (HK$855,000). Police said they had recovered 820,000 yuan. Li Zhongxian, a watchman at a nearby school who was outside the store at the time, was shot twice as he tried to stop the men. He was taken to hospital and survived. Acting on information that the prime suspect, Chen Shejie, had fled from Zhengzhou to Shijiazhuang, Hebei province, more than 50 police officers from Zhengzhou were despatched on Monday to Shijiazhuang. The following day, a team of 20 officers raided a local hotel and arrested Chen and his wife. According to police, Chen later confessed to the crime and led investigators to his accomplices, Yang Junchao and Li Tianbiao. Officers arrested them on Tuesday in Kaifeng after a province-wide search of Henan. The newspaper said police later arrested five more in connection with the robbery. The robbery came as an embarrassment to police in Zhengzhou and prompted them to round up hundreds of suspects, including those who may have sold the robbers explosives, in an effort to hunt down the culprits. On Tuesday, Zhengzhou police chief Zhang Chengfeng said the arrests were testament to the 'high standard and professionalism' of the force.
