HELP.

Hey!
I had to call the cops on my neighbor today. I turned her in to social services last week. I turned her in but I didn't state my name and I had it written in Swedish. There is no way she would know who did it.She screams to her newborn to shut the fuck up. She has a history of violence with her ex sambos. She yells and screams. I am a pediatrician and I feel that it was my duty to call.  
She also has on several occasions verbally attacked me for no reason. Shes called me a bitch and told me to move back to my country. It started because I asked her if she could turn her bass down as my desk meets her living room wall. Since then she is usually mean to me. I left a note another time letting her know that her dog had been barking all night. Other neighbors have complained about the dog barking and loud noise. She even has been spoken to by our housing leader. (We own our apt)

So we've been hear terrible sounds and I've talked to other people about contacting someone because I think she needs help and they baby isn't safe. I mean who screams at a baby to shut up. Last week she at 3 am she was fighting with someone and we heard glass break on the wall and the baby went silent and then screamed for hours. 

Today I was contacted by our housing leader who said he got an email from her wanting the board to step in and settle our issues. This was strange as I am very nice to her.. I hold the doors open and say hello. I've not given her any reason to think I hate her etc. So I thought well if shes wanting to solve this I will just knock on her door and tell her I have no problems with her and give her a baby gift. So I told my sambo I was going to do that. While I was saying that the baby started screaming and she kept screaming shut up fitta and then the baby screamed really loud. So I thought ok I will give the gift (we are also expecting so I had a baby toy already).. I would also stop this yelling and tell her we have no problems. I was going to offer to take her dog out as well... because I have actually helped her with her dogs in the past. 

So I went over to do this. The woman opened the door screamed at me and said she wanted nothing to do with me. Mind you I had just said hello. The baby was in the stroller and she was still crying. The woman shook the stroller so violently that the dog reacted. (This was all voice recorded on my phone). I left and called my sambo who said to call the cops. I did and when I was spelling the names out from their mail box the mother, who had left, came back and realized what I was doing. She left her baby outside and drug her dog who was crying (she hits her dogs and people have reported her). She slammed her door and while I finished spelling she ran out of the house with a car seat and ran out.  The police came and talked to me. They were really worried and so they've sent cars out looking for her and told me an on call social services person and the cops would talk to her and look at the kid. 

I feel terrible about this.. I feel really bad for the kid. I am afraid of this woman and I don't know what I can do. I'm afraid she will slash my tires.. or something else. Should I not have called the police? Should I have just wrote another anonymous report? How can I protect myself from her. Moving is not an option our child is due soon.
