Two men have been caught attempting to smuggle hundreds of Chinese teenagers into Costa Rica, Beijing police said yesterday.

Cen Shuiman, 43, and Zheng Anqiang, 36, both from Guangdong province, forged visas and application materials for more than 300 people, mostly teenagers, police said.

The human traffickers, which are better known as snakeheads, had worked with foreign counterparts, police said. They were detained earlier this year.
