<human>: he is currently on probation for assaulting his two younger siblings a few months ago whilst very drunk and is now homeless because he is not allowed to go back to the house. he came to my house today saying that he had been the bank and they have "stolen" his money (he had his debit card stolen and they can't issue him a new one because he doesn't have a place of residence). his hand had someone else's blood on it and he said he "really hurt" someone at the bank but he "doesn't want to talk about it" so i am not sure what happened.  

i believe his violence is due to the abuse in his childhood and drug addiction (currently using dope). should i encourage him to tell the police or his probation worker than he's committed another assault? is he likely to be able to receive treatment for mental illness and drug addiction rather than punishment? i am a little scared to be around him now but want him to get the treatment he needs and i don't know the right thing to do.

Provide a brief overview of the text.
