Staff have voted to refuse to teach a pupil who has been allowed to go back to a school after threatening other children with a knife.
Saltley School in Birmingham originally permanently excluded the teenager, but the decision was overturned by its governors.
Head teacher Balwant Bains confirmed a "very serious" incident had been dealt with "through due process".
Police said they took "no further action" after an incident involving a pupil and a knife on 22 May.
