At least nine demonstrators were killed, and many others wounded. Escalating the incident, on June 23, 1925, a heated demonstration in Shameen Island took place which resulted in the Shakee Massacre. Troops under foreign command, perceiving shots being fired at them, killed more than fifty Chinese protesters and wounded almost two hundred more.
