2012 Saudi Arabia mass trespasses
The 2012 Saudi Arabia mass trespasses, known by its instigators as The National Day to Invade Dwelling Places of Jinn (Arabic: اليوم العالمي لغزو الجن, romanized: al-Yawm al-ʿĀlamī Liġazū al-Jinn) was a campaign by a group of several Saudi paranormal investigators to conduct surprise raids and storm suspected haunted sites across several cities in Saudi Arabia on 21 May 2012. The self-proclaimed ghost hunters had planned mass incursions into abandoned locations in Dammam, Khobar, Riyadh, Jubail, Hafar al-Batin, Najran, Jeddah and Tabuk and were partly successful before the Saudi law enforcement agencies foiled their attempts.
