Second suspect arrested over deadly Sweden school attack

Swedish prosecutors have apprehended a second person suspected of involvement ​in last week's attack at a school ‌in which a 17-year-old girl was killed and three people were injured by a ​man wielding a sword, they ​said on Wednesday.

On Friday, police arrested ⁠an 18-year-old man they said was ​believed to have carried out the attack ​at the Brinell high school in the central Swedish town of Fagersta, and launched an ​extensive investigation.

The second man was ​held on suspicion of accessory to murder and ‌accessory ⁠to attempted murder, and a decision will be made on Thursday on whether to ask a court to formally ​detain him, ​the ⁠prosecution authority said in a statement on Wednesday.

The agency did ​not say how the second ​suspect ⁠may have aided the attacker.

A source on Saturday said police were investigating whether the ⁠18-year-old ​attacker was involved in ​online communities promoting school violence.
