On May 23, a passer-by was injured by a knife falling from a high altitude in a community in Fuzhou, Fujian. The property staff said that the security department of the property had started to deal with the matter as soon as they knew it, and the perpetrator had not yet been found. Gao Tingting, a lawyer from the Bank of China Law Firm in Beijing, said that the crime of throwing objects at high altitude did not take the actual result as the filing standard. If the throwing person has repeatedly thrown or the throwing objects have greater harmfulness, the conviction of the crime may be upgraded to the crime of endangering public security by dangerous means.
