Meanwhile, the negligence of the police and the accused collusion with the criminals during Yuen Long attack on 21 July, had spread the protest into Yuen Long, a satellite town in the New Territories. Under Public Order Ordinance, protests are required to obtain the Letter of No Objection to stage a rally or protest. However, the police instead issued a Letter of Objection days before, declaring any such protests illegal . Nevertheless, many citizens still gathered there. They expressed their criticisms of the police by visiting Yuen Long with excuses such as shopping. Some of the protesters engaged in violent actions during 27 July protest. However, when the protesters were leaving and retreating upon police request, the police also used force to try to arrest protesters. Once again, pan-democrats lawmakers had signed a petition to condemn the violence of the police and accuse the force used by the police during the clearance of the location of nearly engaging in a revenge (). They also stated that issuing Letters of Objection would create a vicious circle that only would instigate more citizens to protest.
