GUANGZHOU - MORE than 600 people in the Chinese city of Guangzhou have been arrested and scores of stolen vehicles seized, police authorities said, amid a security crackdown ahead of the Asian Games.

The Ministry of Public Security said it had arrested 611 'fugitives' in the southern city, without providing further details.

Police had so far searched more than one million vehicles and boats and three million people entering Guangzhou as security was tightened ahead of the Games, the ministry said in a statement Saturday.

Guangzhou has been gearing up for the Asiad - the world's biggest sporting event after the Olympic Games - that takes place from November 12-27 and will be attended by nearly 12,000 athletes from 45 nations and territories.

Authorities have implemented a number of strict measures to ensure the success of the Games, including traffic restrictions that aim to take half of the city's vehicles off the roads.
