Ten Injured as Primary School Wall Collapses During Independence Day Event
The boundary wall of SDN Minomartani 2 in Ngaglik, Sleman, collapsed suddenly while residents were resting nearby after taking part in a community walk and exercise session on Sunday (9/8/2026). Ten residents were injured in the incident.
Sleman Police Public Relations Head Inspector Argo Anggoro said the incident occurred at around 7.50 a.m. Western Indonesia Time in the Minomartani housing complex, RT 06/RW 02, Mlandangan, Minomartani. At the time, a number of residents had just finished a community walk and exercise session held to commemorate the 81st anniversary of Indonesian independence and were sitting near the school fence.
“The wall then collapsed and fell on residents who were in the vicinity. The incident resulted in ten residents suffering injuries,” Argo said when contacted on Monday (10/8/2026).
The ten injured victims consisted of seven women, identified as AS, S (64), KM (70), ADS (34), SL (40), FN (30), and BR (28). The other three were men, namely AN (31), L (SL’s child), and LSAF (34).
They were immediately evacuated to receive medical treatment. Argo said six victims were initially treated at Condongcatur Hospital, two were referred to Hermina Hospital, and two others received treatment at UAD Hospital.
“A number of victims were subsequently referred for further treatment,” he said.
“The Sleman Regency Government has also stated that it will cover the medical costs of the victims, while the Sleman Regency Education Office will rebuild the barrier with stronger and safer construction,” he added.
Based on the results of the crime scene investigation, the collapsed wall was approximately 1.5 metres high and about 20 metres long. The section of fence that collapsed was around 12 metres long. The wall was made of cement breeze blocks and is estimated to have stood since around 1980.
Officers at the scene also found that the wall’s construction lacked adequate foundations and steel reinforcement. At the time of the incident, no one was carrying out any activity or in contact with the wall.
Nevertheless, police are still investigating the exact cause of the wall’s sudden collapse.
“At the time of the incident, no one was found to be carrying out any activity or in contact with the wall. To date, the exact cause of the wall’s collapse is still under investigation,” he said.
The public has also been urged to exercise greater caution when carrying out activities or gathering near buildings, walls, fences, or facilities that are old, especially those showing signs of damage.
