Hi. I have a really serious problem. Last year, my girlfriend's little sister, who is 15, broke up with her boyfriend after he sexually and physically assaulted her. He began a campaign of harassment by phone ringing and texting her on a private number. When she told my girlfriend she was thinking of killing herself, my girlfriend and her brother took her to the police in St Mary's. The police didn't want to know about it and told the 15-year-old "we'll arrest him but if you've ever hit him, we're going to arrest you, too". She got scared and left since all he had to say was she had hit him to get her arrested and he probably would have. Two days later, my girlfriend and I took her sister to Parramatta to see friends. Her ex-boyfriend was with them and my girlfriend spoke to him about what he was doing and told him to stay away from her sister. The guy laughed and smirked about the allegations and called my girlfriend a slut. I stood between them and told him to leave but he just laughed. I walked forward with my hand extended but not touching him and he walked backwards laughing and smiling saying, "you can't touch me. I'm just a kid." He then turned around and went to his friends. I followed behind to make sure he didn't return. His friends then came over. One produced a knife and held it toward me yelling, "I'll kill you." I put my hand above my head and indicated towards the armed person and yelled "Knife, knife, knife." Security turned up and I told them what happened. They wanted us all to leave but I told security they should call police because of the knife. The police arrived and I told them what had happened and they told me they wouldn't arrest me but then this one policewoman turned up. She didn't ask any questions about the incident, went and checked CCTV then came back and arrested me. I was taken to Parramatta police station at 6:45pm and kept there till 1:30am. I was denied phone calls, refused access to a lawyer though I asked so many times for both the sergent had another prisoner threaten to stab me. I refused to give a statement without a lawyer. My girlfriend called sometime during the night and the arresting officer gave her a fake message from me saying "I'm fine, I'll call you when I get out". I was charged with common assault. I didn't realise at the time but the same officer banned my girlfriend and her sister from the whole of Parramatta for 24 hours and did not take a statement from either. I complained to police and then the ombudsman because the police refused to investigate. The ombudsman ordered the police to investigate, but they have refused. I have been going to court for 7 months now and the whole time the police have maintained they have CCTV and on the last mention opposed my application to vary bail telling the magistrate "We have CCTV footage showing the assault, your honor" but when they finally gave me the brief, it states the CCTV footage was destroyed last November. The police officer who arrested me has created a statement completely different to the police facts and put in there a fake confession as well as changing the original "placed his hand on the victim" to "struck the victim", etc. After the incident my girlfriend's little sister met up with one of her ex-boyfriend's friends who she also was friends with. They met in a park and the friend pushed her onto the ground and raped her. I'm pretty screwed. Any help with Criminal Law would be good.
