Dunne was found guilty of four counts of conduct that prejudiced horse racing.
The jockey was found guilty of harassing another jockey.
Dunne was found guilty of four charges of conduct that were against the reputation of horse racing.
The British Horseracing Authority brought charges about a "weighing-room culture" and the panel heard evidence about it.
Dunne was guilty of "distasteful targeting, deliberate harassment on and off track, and occasional cases of dangerous bully", said Brian Barker.
Barker said that a deliberate conduct over a course of time has been revealed.
He said the panel had real concern about the culture of the weighing-room.
Sanctions against Dunne have not been decided.
What evidence has been heard?
Louis Weston said in his closing remarks that Dunne subjected Frost to a "vendetta".
Weston said that the treatment of Frost by some colleagues since she made the complaint has been "outrageous".
Weston said Dunne used "foul, sexually abusive and misogynistic language" towards her and threatened to cause serious physical harm.
Dunne shook himself in front of Frost in the men's changing room, where female jockeys would sometimes go to collect kit.
Dunne said that being naked was not a sexual act and that she only remembered being undressed in front of her when walking from the sauna to the weighing scales.
The case was a jigsaw puzzle with many missing pieces, according to the closing remarks by Moore.
The leak to the Sunday Times of the investigation report had a massive effect on Mr Dunne's health and welfare, he said.
Dunne had denied two of the three counts of violent or improper behavior.
Dunne said he was using a "figure of speech" and not a threat when he said he would put her through a fence.
Weston wondered why other riders hadn't seen anything different from the exchange.
If there is a weighing-room culture that allows one jockey to threaten another with serious harm to them and their horse, that culture should be thrown out and discarded. He said that it's had its time.
He said that racing made people feel pressured to speak freely.
Dunne was found guilty of the more serious charges and the panel set aside the violent or improper conduct charges.
More to come.
