The Swedish police detained one on Friday after a sword attack in the afternoon injured several people at the Brinell School in Fagersta, central Sweden.
The male suspect was reportedly shot in the leg before the Swedish police captured and detained him, local media reports said.
“A call was received regarding a case of ongoing deadly violence at a school in Fagersta. Police are continuing to work at the scene with a number of different resources," the police said in a statement, as per a Reuters report.
Police and rescue services were dispatched to the area at about 2 PM CEST (5:30 PM IST).
A helicopter has also reportedly been involved amid an ongoing large police operation at the school as of 4 PM CEST (7:30 PM IST), with multiple resources deployed to the area.
"The public is urged to respect the roadblocks and listen to police instructions," the police statement added.
Brinell's capacity is said to be just under 500 students, who had been kept at the locked-down school amid the police operation, as of 3:45 PM CEST (7:15 PM IST).
Several schools within the vicinity of the Brinell School also went into lockdown as the police operation continues, the Fagersta Municipality said in a statement.
"A serious incident has occurred today in Fagersta at a school, just after the summer holidays ... We do not yet know what is behind the act, but we know that the police are working very intensively ... Our thoughts are with all those affected, Swedish PM Ulf Kristersson told news outlet SVT.
Notably, this is the second incident of school violence in Sweden this week after a minor was shot at the Ronna School in Södertälje.
Three suspected perpetrators were arrested in connection with the crime, of which two were minors as well.
"If it turns out that this is gang-related, it is a reminder that there is no room for society to back down in the fight against gangs," said Sweden's Justice Minister Gunnar Strömmer.
