South China Morning Post ↗Authorities say police prevented a third school attack

The Hindu ↗How it started
The first attack took place on October 7 at Vocational School Complex No. 4 in Ostroleka. A student aged 19 injured eight people at about 11 a.m. local time, according to The Hindu, citing police.
The injured included students and teachers, Arab News reported. Police detained the suspect. Two victims were in critical condition, according to nu.nl.
The injury count differs across reports. Telegraaf reported seven injured, citing police, while South China Morning Post reported 10, citing the town's mayor. The latter count included the suspect.
How it unfolded
On October 8, a second attack took place at a school in Leszczydol-Nowiny at around 0700 GMT. A 37-year-old woman who worked as a caretaker was killed, according to NDTV Top Stories.
The suspect was a 15-year-old former pupil at the primary school, South China Morning Post reported. Police arrested him, according to ANSA. TGcom24, citing local media, reported that the school's headteacher had stopped him.
Reports also differ on the number injured in this attack. Sky News reported two people injured in addition to the employee killed, while nu.nl reported three injured. Telegraaf described the two injured people as other staff members.
The second attack brought concerns about imitation. South China Morning Post reported that the suspect wore a helmet-mounted camera and raised the possibility of an internet challenge. The available coverage does not establish that explanation. CNN Brasil also reported, citing authorities, that police had prevented a third attack.
By October 9, the response had widened to threats circulating online. South China Morning Post reported arrests of young people, mainly over school attack threats, as authorities sought to calm fears generated by rumours of a "Bloody Friday".
Where it stands
Police searched more than 10,000 educational institutions across Poland on October 9 and detained 10 people in connection with attack threats, according to Infobae. nu.nl reported that police were present at educational institutions as a precaution after young people threatened school stabbings on social media.
Those threat-related arrests are separate from the reported detentions of suspects in the two school attacks. The Friday coverage describes a broader preventive response, not a confirmed wave of further attacks.
What to watch
The main unresolved issue is whether investigators establish any connection between the two attacks, the subsequent threats and a possible online challenge. South China Morning Post presented the challenge explanation as a possibility, not a confirmed motive.
A reconciled casualty count is also needed. Reports of the first attack range from seven to 10 injured, while reports of the second give either two or three injured alongside the woman killed.
