A burglar who stabbed a security guard five times at an elite Brisbane girls' school allegedly borrowed a woman's phone to call a taxi as he fled the scene on Wednesday morning.
Detective Inspector Tony Geary said Khia Gribben, 25, fled Somerville House in South Brisbane soon after the incident.
He allegedly borrowed the woman's phone at nearby South Bank station and used it to arrange a taxi to meet him when he got off the train at Albion, in the city's inner north.
The 25-year-old was last seen getting out of the cab outside the Lutwyche Shopping Centre about 6am, 40 minutes after the attack.
Insp Geary said Gribben, who is known to police, had no links to the school and was believed to be on the property for the sole purpose of committing a burglary.
The security guard, who did not carry a weapon, initially thought Gribben was a cleaner.
The woman who loaned Gribben her phone has provided a detailed statement to police, as have several other witnesses.
But Insp Geary urged anyone else with information to come forward, or for Gribben to hand himself in.
"We're confident we will have him in custody in the very near future," he said.
Gribben has links to Brisbane's northern suburbs and the Sunshine Coast.
The security guard remains in Princess Alexandra Hospital in a stable condition.
Police are continuing to scour for evidence at three crime scenes - two at the school and another at South Bank train station, as well as study CCTV footage from countless Somerville House cameras.
