Chinese security guards rescue boy held hostage by knifeman
Suspect had tried to rob the youngster in the street in Guizhou province

Two security guards in southwest China have been lauded as heroes after rescuing a young boy held hostage by a knifeman who tried to rob him.
The guards, Zhu Jiang and Wang Jiahui, subdued the knife-wielding man in Xishui county in Guizhou province last month.
Surveillance footage of the incident was released by the police earlier this week.
Zhu and Wang were heading home for the day after work when a boy told them there was a man brandishing a knife nearby, the news website Thepaper.cn reported.
Zhu got his wife to call the police and the two guards found the man holding a knife against the neck of a shirtless young boy.
The man, 19, yelled at them to leave, threatening to kill the boy.
Zhu, a security guard at a local hotel, asked the man if he was short of money and offered him 500 yuan (US$75) to release the child.
