Chilling CCTV pictures have emerged showing a Chinese man armed with a meat cleaver attacking first- and second-graders at a school in central China, injuring eight.
The government of Macheng city in Hubei province said the man, identified as 35-year-old Chen Zuihang, was detained following the attack. It said on its website that police were investigating the motive.
The statement said the injured students were being treated at a hospital.
The CCTV pictures emerged as news unfolded of another stabbing spree in the Henan province, where a dispute between neighbours ended in seven deaths in the Lushan province.
China has suffered a series of attacks on kindergartens and grade schools, often by people who are mentally ill or are angry at society.
Last month, a group of eight knife-wielding men slashed at students on their way home, killing one student and injuring two in the northwestern city of Ankang.
Last year, a man injured six pupils and one parent with a kitchen cleaver in the southern city of Maoming.
Education officials have ordered tighter security at schools throughout the country.
