Yet Tomic has now hit back in an interview with the Herald Sun, stating: "I have never threatened his family".
Bernard Tomic denies he threatened Lleyton Hewitt's family and has labelled Australia's Davis Cup captain a liar as the ugly feud engulfing tennis in this country continues to escalate. Additionally, Hewitt asserted firmly that Tomic would not play Davis Cup again as long as he was in charge.
In a media conference following Hewitt's loss in the Australian Open doubles competition, the two-time Grand Slam victor fielded questions about Tomic's accusations that Hewitt was giving preferential treatment to other Australians when it came to Davis Cup selections and that he had a conflict of interest within Australian tennis.
Tomic and Hewitt have been feuding since Tomic claimed Australia couldn't win Davis Cup matches without him, and Hewitt refused to select him.
"Both (physical and verbal) - blackmail and physical", Hewitt said.
I think the threats that I've received for me and my family that I've had for a year and a half now ...
"It was probably the abuse I copped", Hewitt said in the press conference. "I had to draw the line".

Speaking on Monday, Tomic said: "No one likes him any more".
Hewitt went on to describe Tomic as "a clown" and lamented the amount of time he had spent trying to help the 26-year-old.
"Since then, I haven't had anything to do with Bernie..."
Tomic and Kyrgios will never be included or remembered for being in the same ranks as the powerhouse players: Nadal, Djokovic and Federer (and Hewitt when he was at his prime) as they are show ponies.
"To me, it is very, very sad when you have people like Rod Laver, who the main stadium is named after sitting court side most days, you have got ornaments like Evonne Goolagong-Cawley, who was just class personified when she played, and yet we have this wave of tennis players who are fortunately on the way out". Tomic, however, went a bit further, suggesting Hewitt has a personal interest in players he is promoting.
Australia's qualifying tie next month in Adelaide is against Bosnia and Herzegovina and Nick Kyrgios is also unlikely to play a role due to his sliding ranking and his attitude.
"The biggest thing "Rochey" (Cup coach Tony Roche) I have is to set cultural standards and I feel Nick isn't meeting those".
Following the games, however, the duo used their post-match media conferences to pour gasoline all over the mound of Australian men's tennis and light it on fire, for reasons that appear about as visible as the fart of a ghost. With Bernie, you know, things have been coming out for a while.
"It's not easy if you don't get the support from certain players, but Lleyton has won more battles than that".
