Strangeworld, I think I read the arrested man had been staying with a relative (uncle), but I don't think it was in Logan - some other area around Brisbane.
I was surprised yesterday when channel 10, NBN and ABC 24 didn't blur out his features in the footage of him being lead to the car by police. He had the blanket around his face, but you could still see stuff.
Might be mistaken but there appears to be some PNG connection with the offender from what's written on that page showing his picture, plus the short tight curls.
If the police case is strong and its proven that this person is responsible for the crime, I feel sorry for his family knowing that not only has he committed such a brutal act, but that he has lied even to them. If convicted he knows his life's over anyway, so maybe by denying involvement he thinks he has a chance.
I don't imagine police would arrest somebody this quickly without having some pretty rock solid evidence though. If he was arrested during those riots maybe they took prints back then which matched the crime scene.
I also agree the identikit picture of the other rapist looks to be a different offender based on the hair.
