Upon discovering that his father was seeing prostitutes, a young security guard surnamed Guo, who is working in Changzhou in east China's Jiangsu province, decided to stop him. He bought a full SWAT costume, fake SWAT certificate, plastic pistol, toy handcuffs and electric baton online and disguised himself as a SWAT officer. He patrolled the streets and stopped any possibility of his father buying sex.

According to the local police, a man complained to the police on Jan. 1, saying that a SWAT officer patrolling the street had frightened his dog with an electric baton. The local police went immediately to the scene and caught the SWAT imposter, Mr. Guo.

Guo, 21, has worked as a security guard in Changzhou since 2013. He said that he dreamed of becoming a police officer for a long time. He came up with the idea to disguise himself as a SWAT officer after he found out about his father visiting prostitutes. On Jan. 1, Guo's father called him to ask for money. Guo refused him as he thought that his father might use the money to visit prostitutes again. Angered by the idea, Guo put on his costume and went patrolling in the street in order to "frighten the prostitutes and drive them away from [his father]."
