T.I.'s argument with a security guard in his gated community has amped up ... he's been charged with 3 misdemeanors.
Prosecutors in Henry County charged the rapper with simple assault, public drunkenness and disorderly conduct stemming from his arrest back in May, when a security guard refused to let him into the premises. T.I.'s lawyer, Steve Sadow, tells TMZ the charges are "baseless, ill-founded and unjustified."
A source with direct knowledge of the case tells us ... T.I. likely faces no jail time.
Sadow also says the security guard, Euwan James, "was fired for the way he handled the situation with T.I.," in a statement that was first reported by the Atlanta Journal-Constitution.
As we first reported ... the security guard called 911 and said Tip was threatening him and asking him to step outside of the guard shack. T.I. was adamant he did not deserve to get arrested ... saying as much to cops.
