As an off-duty SWAT officer was shopping with a friend in Chengdu, he saw a suspicious looking man and started to keep an eye on him. As the officer had expected, the man suddenly rushed up to a woman and grabbed her purse. The officer sprang into action, chasing down the man and restraining him. As he was being held on the ground, the man started to bash his head on the ground and bite his tongue to make it appear as if the officer had beat him. After the woman recovered her purse, she snuck away from the scene, making it difficult for police to press charges against the man.
