LeBron James' mother slapped a Miami Beach valet so hard in the face, she lost her balance and fell to the ground -- then told a police officer, "I don't trust your kind" ... this according to the police report.
The arresting officer says he tried to question 43-year-old Gloria James about the alleged incident at the scene early this morning ... but he got "no response just a stare." After a while, she eventually admitted to having a "minor verbal altercation" with the valet.
The cop says the valet explained that he retrieved James' car and put it on the valet ramp in front of the hotel while Gloria and a female driver stood around talking to people for 30 minutes. Finally, the valet says he turned the car off.
The valet says Gloria then approached him and stated, "Where are my f**king keys and continued yelling profanities at the victim."
The report explains, "Then for no apparent reason the arrestee struck the victim with an open had [sic] across the right side of his face and in the process causing herself to lose her balance and falling to the ground."
After Gloria was transported to a nearby police station, the report continues, a shift commander -- Lt. Acosta -- tried to speak with James who responded, "I'm trying to trust you but I don't trust your kind ... I don't trust that officer who arrested me."
Gloria then told police she "was not going to cooperate because she did nothing wrong."
UPDATE: Police have released a photo of Gloria being taken into custody.
