Four boys arrested after wet tissue attacks on passers-by at Hong Kong parkFour boys aged between 12 and 14 were arrested on 22 July on suspicion of common assault over a series of alleged attacks on passers-by in Hong Kong. Another clip showed an elderly man warning the youths that he would call the police if they continued throwing objects. The caller said a 71-year-old male cleaner had allegedly been attacked by three to four youths throwing objects inside Tsuen Wan Park, while other passers-by were also harassed. Investigators believe arguments over the use of the cycling track and other facilities in Tsuen Wan Park may have led to the confrontations. Police also seized bicycles allegedly linked to the incidents, mobile phones, and clothing believed to have been worn during the alleged attacks.
