A Chinese woman who reportedly went on a slashing spree with a blunt ruler, injuring eight pre-school children at a nursery school has been arrested.
Police in Shanghai have apprehended the woman who carried out the attack in a school on Monday, state run Xinhua news agency reported.
The woman, a native of east China's Anhui Province, was a nursery worker at the Xiaofuxing Pre-school Children's Nursing Center in the township of Huacao, Minhang District, a district official said.
She allegedly slashed five boys and three girls with a self-made steel ruler in what was regarded as a social revenge attack, which gripped China last year in which frustrated people targeted school children.
Two such attackers were given death sentence and the official media has been asked to stop reporting such incidents to prevent copy-cat attacks.
The injured children were being treated at the children's hospital under Fudan University, and none sustained life-threatening injuries, he said.
The nursery school operates for children of migrant workers, and further investigations are underway, the report said.
