<human>: Summarize the given text in a few sentences.

Looking for some advice on the following situation.  I overheard my neighbor yelling at his girlfriend and calling her a bitch over and over again, possibly hitting her too.  Something about money and her calling someone.  The police were called, they came very quickly, and later said they couldn't really do anything about "the noise" because they didn't hear it which I guess is code word for "she denies him abusing her".  The police are gone and it's pretty quiet now.  Should I try to record it from the hallway the next time this happens?  Should I call the landlord?  My biggest concern is her safety.  Thanks.
