On 21 July 2019, a mob of men dressed in white and carrying wooden sticks and metal pipes entered the MTR's Yuen Long station and assaulted people indiscriminately. The attack is largely believed to have been carried out by pro-Beijing paid thugs. One pregnant woman was hurt and found lying on the floor, and journalists were also attacked. The mob entered the paid area and attacked commuters aboard a train, which was unable to depart. Over 40 people were sent to hospital. After the incident, pro-Beijing legislator Junius Ho was accused of supporting the attack.
