A 16-year-old girl has been charged after three teachers were taken to hospital as a result of a disturbance at a school in Scotland. Officers were called to Johnstone high school in Renfrewshire after a former pupil entered the school at about 10.45am on Friday. Three female teachers aged 34, 48 and 59 were taken to Royal Alexandra hospital in Paisley and received medical treatment for minor injuries. A 14-year-old pupil was also injured and received medical assistance. A parent at the school told BBC Scotland there has been issues with violence and vandalism for a number of months. He said: “The toilets are now permanently closed to all pupils, as they have been completely vandalised and taken out of use on numerous occasions. “I have total sympathy for the headteacher, who I believe does an excellent job in very difficult circumstance.” Renfrewshire council said the school continued to operate as normal and that any staff or pupils who were affected by the incident were being supported. Mike Corbett, the NASUWT Scotland national official, said: “While the full circumstances of this incident are yet to be made public, we have raised repeated concerns about the vulnerability of teachers to violence and verbal abuse from pupils. “Teachers have reported to us that the prevalence of poor behaviour appears to have increased since the pandemic and that in too many cases they do not feel adequately protected at work.” In a statement on social media, Renfrewshire council said: “A pupil and three teachers were injured and received appropriate medical treatment following an incident at Johnstone high school. “The school continued to operate as normal and senior staff are providing any support needed to staff and pupils impacted by this incident. Parents and carers have been informed.” A Police Scotland spokesman said: “Around 10.45am on Friday, police received a report of a disturbance at a school in the Johnstone area of Renfrewshire. Officers attended and four females aged 59, 48, 34 and 14 years were found to have sustained injuries as a result of the incident. “The three women aged 59, 48 and 34 years were taken to the Royal Alexandra hospital in Paisley. “A 16-year-old girl has been charged in connection with the incident and will be reported to the Scottish children’s reporter administration.”
