It is reported that over 100 people of a mainland tourist group had controversy with the local tour guides on a tour spot in Macao when, according to the tourists involved, the guides forced them to pay for excessive activities not on the schedule (so that the guides may earn backhander). Otherwise, the guides threatened, they would have no food for dinner as well as no place to live. The furious tourists disputed with the tour guides, and soon a police arrived, but during the chaos one of the four tourist leaders was pushed onto the ground, consciousness lost. Some tourists accused the police of using violence while it’s also reported that a group leader slapped on the face of the police. More than 10 police officers soon arrived. [Full Text]
