Aug. 21 (UPI) -- A man wielding a sword entered a Swedish high school and injured three people Friday before being shot and arrested by police.

Police were called at 2 p.m. local time at Brinelskolan School in Fagersta, Sweden. The students had just returned from summer break this week.

Two of the three people were seriously injured. Local media reported that the attacker was shot in the leg by police, the BBC reported.

Eight other area schools were put on lockdown, but that has since been lifted. A state of high alert was declared for the Vastmanland region. Fagersta, a town of about 12,000 residents, is about 105 miles northwest of Stockholm.
