Responding to the incident at Milford Haven Comprehensive in Pembrokeshire, Matt Wrack, General Secretary of NASUWT – The Teachers’ Union, said:
 
“Tonight, we hold the injured teacher and the community of Milford Haven Comprehensive School in our thoughts.
 
“We are distressed to hear that following the incident, a young person has been arrested on suspicion of attempted murder. Schools should be places of safety and learning – not fear and violence.
 
“The coming days will be very challenging for everyone at the school, and as The Teachers’ Union, we will be standing by to offer all the support we can.”
 
Neil Butler, National Official for Wales, said:
 
“With increasing regularity, teachers are arriving at school in their own cars but leaving in ambulances. Today’s events are frightening.
 
“Teachers sign up to become stewards of the next generation, and to share their joy and passion for education. We must remember that like everyone else, they are entitled to be safe at work.
 
“We wish the injured teacher a full and swift recovery. But it may not be that simple. As violence in schools increases, teachers will need more than hopes and prayers.”
