An abduction suspect on the most-wanted list has been arrested, the Ministry of Public Security said Wednesday.

Wu Qiuyue, 52, was captured on Tuesday in her hometown Anxi County of Quanzhou City in southeast China's Fujian Province by local police.

She was involved in a human trafficking gang the police smashed in February. Police rescued 29 children and arrested 13 suspects in the crackdown, but Wu ran at large.

On June 4, the ministry issued a class-A warrant for Wu. On December 15, more than 100 police officers started searching for Wu and seized her seven days later in a cave in Jiandou Township, Anxi County.

So far, 19 out of 20 suspects on the ministry's most-wanted list of serious abduction crimes have been arrested.

In another development, the ministry on Wednesday launched a 100-day nationwide winter campaign to ensure order and stability for the incoming Lunar New Year holidays.

Serious criminal crimes should always be severely cracked down upon, said Vice Minister Zhang Xinfeng.
