Australain tennis player Bernard Tomic has brushed aside Llyeton Hewitt’s claims of threatening the Davis Cup captain's family, calling Hewitt a liar.

"I have never threatened his family," Tomic said speaking to News Corp Australia.

Bernard Tomic“Nice, Lleyton. To think how low of a person you actually (are) and (it’s) why the Australian public never liked you. I got nothing to do with your family and I don’t care what’s wrong with you, you liar.”

Tomic was responding to Hewitt’s allegations as the ugly feud in Australian tennis escalates.

The war of words started when Tomic after started his verbal volley against the former world No.1 following his first-round Australian Open loss on Monday.

In return Hewitt said that Tomic would never play Davis Cup again as long he is there after physically threatening him and his family.

After his Australian Open doubles exit, Hewitt said he'd cut all contact with Tomic after the alleged which has been continuing since the past 18 months.

Hewitt called Tomic ‘clown’ and described him as a ‘lost cause’.

Llyeton Hewitt“I don’t think anyone would reach out to a person who speaks like that. For me, it was the abuse I copped from him at the end. I drew a line in the sand, and I haven’t spoken to him since. He won’t play Davis Cup while I have anything to do with it.”

Hewitt said he did try to help Tomic but was frustrated with the futile effort.

"I spent a lot of time with him at a lot of tournaments and tried to get a coaching structure and physical team around him to give him the best opportunity but at the end of the day he kept making the wrong mistakes," Hewitt said.

Llyeton Hewitt“Deep down, Bernie knows what I’ve done for him ... for Bernie to come out and have a go but more to get all of his facts wrong, that’s probably the most disappointing thing.”
