A manhunt is underway for an intruder who repeatedly stabbed a security guard at an elite Brisbane girls' school before fleeing, possibly on a train.
The guard, aged in his 50s, was attacked after disturbing the intruder at Somerville House in South Brisbane about 5.30am local time.
He has knife wounds to his lower and upper abdomen and his sides, the ambulance service says. Police say he was also stabbed in the arms and while his injuries are significant, they are not life threatening.
Police are scouring the school grounds and searching surrounding areas for the attacker, who initially fled on foot but may have boarded a train during his getaway.
Detective Inspector Tony Geary says the attacker could still be armed, and is likely to have blood-stained clothing. He's warned members of the public to remain vigilant amid suspicions the offender may have boarded a commuter train during his escape.
