TMZ broke the story last night and we updated you on why Justin Bieber was allegedly being charged with battery after a heated altercation with a neighbor.

At that time the story was a little foggy on weather or not the neighbor got mad because of Biebers top notch speeds throughout the neighborhood or because of parties thrown while he was on tour.

Update: 

TMZ has learned that the man who confronted Justin told Sheriff's deputies that the singer was driving "unbelievable recklessly" through the neighborhood in his Ferrari.

The man (whose hobby is racing cars) estimated Bieber's speed at 100 mph. 

His wife was out walking the dog at the time and there are kids on the street because of Spring break putting several individuals at risk. Multiple neighbors back up his story….

We are told that the man was NOT upset by the partying at Justin's house, saying it was "no big deal." But he admits that he was "smoking hot" when he went to Justin's home to tell him how inconsiderate he was by driving at breakneck speed.

The man who is 5'7" and 135 lbs claims that Justin did make some sort of contact with him and thus the battery allegation.

BTW Justin was pictured blowing a red light in Calabasas just hours after the altercation.
