Two schoolgirls were yesterday expelled after being arrested on suspicion of plotting to murder their maths teacher.
The girls, aged 14 and 15, were allegedly heard discussing a knife attack on Alison Cray, 46.
It came days after the killing of teacher Ann Maguire, 61, in Leeds.
The 15-year-old was also arrested on Thursday on suspicion of having a knife and making death threats.
The pupils, who have been bailed, will be moved from Cwmcarn High School, near Newport, to a special education unit.
A council spokesman confirmed: “Both girls were permanently excluded.”
The elder student joined a protest 18 months ago to keep her school open when asbestos was found in the building.
Miss Cray and school governors praised the swift action.
Chairman Gary Thomas said: “We thank parents for their positive calls.”
