A Wollongong man has denied allegations he threw a hammer at his pregnant girlfriend, leaving her bleeding from a deep head wound.
A furious James Dalton spat at the AVL camera and called Magistrate Geraldine Beattie a "f--king dog" after being refused bail in Wollongong Local Court on Thursday.
"I didn't touch her", the 27-year-old said indignantly, claiming the alleged victim had inflicted the injuries on herself.
Documents tendered to the court said the woman was at Dalton's Smith Street unit on the morning of June 24 when she discovered a used condom and female underwear that didn't belong to her and accused Dalton of having an affair.
The pair got into a heated argument and the woman packed some belongings, intending to leave.
However, it is alleged Dalton barred her from leaving, prompting the woman to begin throwing her belongings off the balcony.
It is alleged Dalton threw a hammer at the woman's head during the argument, hitting her in the forehead.
He then allegedly tackled her to the floor and put his knee on her chest to hold her down.
The woman was screaming and crying but eventually managed to break free and ran from the home.
Once in the driveway, the woman realised she was bleeding from the head.
Police attended the scene a short time later and took a statement from the woman, however Dalton had allegedly fled before they arrived.
Police noticed the woman was bleeding from head, had a large lump on her forehead and had scratches and red marks on her neck and shoulders and a large bruise to her chest.
Officers returned to the unit at 11.30 that night to arrest Dalton, however he allegedly locked himself in the apartment then jumped off the balcony when they forced entry to the home.
He was arrested after a short foot chase and a brief struggle.
He was taken to Wollongong Police Station and charged with assault, being armed with intent, resisting police and entering inclosed lands.
Officers will allege Dalton was too hostile and aggressive to be interviewed, telling police "I'll rape your kids if I find them".
In court on Thursday, police prosecutor James Sala described the facts as "quite disturbing" and noted Dalton had a lengthy criminal history.
Defence lawyer Adam Booker said Dalton denied the allegations and could live with his father in Dubbo if released.
"He says at not time did he ever throw a hammer, he says there wasn't even one in the unit," Mr Booker said.
The case will return to court at a later date.
