IT teacher, 37, charged after principal allegedly slashed with kitchen knife at Melbourne school

New details have emerged about a teacher who is accused of stabbing a principal at a secondary school in Melbourne.

Police swarmed Keysborough Secondary College in the city's south-east about 3pm yesterday after principal Aaron Sykes, 43, was allegedly slashed in the arm and lip with a kitchen knife by Kim Ramchen.

The court heard today that the IT teacher, 37, allegedly snapped after learning his contract would not be renewed.

Sykes was taken to hospital with non-life-threatening injuries and has since been released.

Ramchen was pulled away from staff who heard the commotion, the court heard.

Staff managed to pin him down after he allegedly returned to the office with a second knife.

The school went into lockdown following the incident.

"Me and my friends, we quickly ran into the food tech room and then we just hid there," one student told 9News.

Ramchen was arrested at the scene and was taken to hospital with a minor injury, where he remained under police guard.

He has since been charged with two counts of unlawful assault, one count of intentionally causing injury, recklessly engaging in conduct placing a person in danger of serious injury and assault with a weapon.

He appeared before Dandenong Magistrates' Court today.

Ramchen's brother told the court his brother is a quiet person and that he was shocked to hear about the alleged stabbing.

Ramchen was refused bail and will return to court on January 6.

In a letter sent to parents, the school said Sykes was "recovering well and is in good spirits".

The school also assured parents that no student was involved in the incident.

"Any form of violence within our school is entirely unacceptable. We are proud of the safe and supportive culture that is the norm at our school," the note read.

"We want to assure you that the health and safety of our students and staff is always our highest priority."

The school has reopened today.

An investigation into the incident remains ongoing.

Anyone who witnessed the incident, has footage or any information that could assist police is urged to contact Crime Stoppers.
