Two students have allegedly been stabbed in two days at Adelaide high schools.
A 16-year-old boy was arrested this afternoon after he allegedly stabbed an 18-year-old female student in her torso at a school in Adelaide's north-eastern suburbs.
Police were called to the scene just after 3:30pm.
They said the boy used a box cutter and scissors in the stabbing.
He is being interviewed by detectives.
The victim has been taken to the Royal Adelaide Hospital with serious but non-life-threatening injuries, including cuts to her abdomen, lower left leg and throat.
Police believe both are students at the school.
