A teacher was seriously injured in a stabbing at Runby School in Upplands Väsby, north of Stockholm.

The attack occurred on school grounds, prompting a swift response from police and emergency services.

The victim, a woman in her 30s, was airlifted to the hospital and is now in stable condition.

Authorities launched a large-scale manhunt, including helicopters and police dogs, but the suspect remains at large after an earlier arrest led to the release of a detained individual.

The school implemented safety measures, keeping students secure indoors, while parents and the community expressed shock and concern.

Police have opened an investigation into attempted murder, but the motive remains unclear.
