A 13-year-old girl has appeared in court accused of attempting to murder two teachers and a fellow pupil in a school playground stabbing in Wales. The deputy head of Ysgol Dyffryn Aman in Ammanford, Carmarthenshire, Fiona Elias; a teacher, Liz Hopkin; and a pupil suffered knife wounds on Wednesday. All have since been discharged from hospital. The girl, who cannot be named because of her age, appeared at Llanelli magistrates court and was remanded into secure youth detention accommodation. She is due to appear at Swansea crown court on 24 May. During a brief hearing before a district judge, Mark Layton, on Friday, the teenager was also charged with the possession of a bladed article. Wearing a grey jumper, she spoke only to confirm her name and address. The school was locked down for about four hours from 11.20am on Wednesday. Dyfed-Powys police have said they are also investigating threats allegedly made by a 15-year-old boy that alluded to the incident. A boy was arrested at an address about five miles from the school. Police said detectives were establishing if there was a link between the alleged offences. Part of another Welsh school, the secondary campus at Ebbw Fawr Learning Community in Ebbw Vale, south Wales, was put into partial lockdown at about 10.20am on Friday after a teenage pupil allegedly received threatening messages. Gwent police said on Friday lunchtime: “Our officers are in attendance. We have arrested a teenage boy on suspicion of making threats. The arrest did not take place on school premises and was not in the Ebbw Vale area. Our inquiries are ongoing.” It is understood that the suspect did not attend the school and no weapons were found.
