Police Detain 76 and Check 50,000 Schools After Poland Attacks

Polish police said Saturday they detained 76 people and checked nearly 50,000 schools nationwide. The sweep followed two school attacks earlier in the week.

• 9 people injured Wednesday when a 19-year-old attacked at a vocational school.
• 1 custodian killed Thursday by a 15-year-old at his former school.
• 59 schools canceled classes Friday, most in Mazovia, the Warsaw region.
• Both suspects are Polish nationals and both are in custody.

Why it matters: Online rumors of a coordinated wave of attacks spread Thursday night. Officials say they found no evidence of an online attack challenge.

• No official confirmation links the two attacks.
• Those detained include teens carrying knives to school in Warsaw.
