A Winnipeg school division says a teacher is recovering at home after being hit with a hammer.
The Pembina Trails School Division said Wednesday the teacher was struck while in class a day earlier at Shaftesbury High School and immediately called for help.
A student who the division says brought a hammer to school was escorted to the office and sent home after the student's parents were notified.
Police said they were investigating, but no arrests were made.
A school social worker was offering support to students.
"We know that witnessing a violent incident can cause trauma and feelings of anxiousness, worry, anger. These feelings are normal. Please know that (Pembina Trails) advisers are available to support students," the division said in a statement, which was sent to parents, guardians and students.
It said students in nearby classrooms heard a commotion and were guided by teachers to take "appropriate measures to remain safe."
Police confirmed they responded to reports that a staff member at the high school had been assaulted.
Officers stationed at the school were on hand to de-escalate the situation and to remove the student before general patrol officers responded.
Police said the teacher declined medical attention.
