I live in an apartment complex for 3 years; I really like my place. I've been married for over 30 years. My husband lives exactly 1 mile from me (he's a hoarder & I need a clean environment, so we don't live together, but remain dear friends).
A month ago my husband was out on a bike ride & stopped by my apartment so we could watch a baseball game on TV. He locked his bike under the stairwell (I live on the 2nd floor). After a few hours he left to go home and found that someone had very tightly zip-tied his bike, in 5 places, to various poles beneath the stairs. We used scissors to release the bike from the zip-ties.
I knocked on the door of the apartment that's just across from the stairwell. A pleasant-looking young man opened the door and my husband asked him if he had any idea of who had zip-tied the bike. The young man went ballistic and started screaming about how the bike created a "fire hazard". My husband pointed out that in no way did the bike create a fire hazard; it was not blocking anything. The guy continued screaming about the bike. I suggested that we speak with the manager. I turned to walk to the manager's door, but noticed that he wasn't home (his truck was gone).
The whole encounter was very weird, but we let it drop and my husband left on his bike.

Then, on an early evening 2 weeks ago the same young man got into an altercation with another neighbor. My husband was here again. We saw the guy standing and screaming long after the other person had retreated into her apartment. We saw him tear at his hair and face. He kept screaming very loudly (could not understand his words). I called 911 and the police came immediately. To make a very long 2 hours short, I'll just say that everything ended up with 3 police cars here (6 officers). The young man was straight-jacketed and taken away in one of the police SUV's. I was relieved, thinking he'd be gone for at least 72 hours, but he returned the following day.

This morning I was sound asleep at 7 a.m. when I heard a man screaming-singing LOUDLY. I've never heard a live opera singer singing at such a volume. That went on for 20 minutes. I finally got out of bed, looked out of the window, and saw some neighbors also trying to see what was going on. I stepped outside, walked toward the stairway a bit, and saw that the person singing/screaming was the same young man, sitting on his motorized bicycle in front of his door. When he saw one of the neighbors look at him the guy went wild, screaming how no one respects his presence or opinion, etc., etc. - while intermittently screaming the same song, over and over. I called 911. Just as I finished the call the guy took off on his motorized bike.

For an hour he repeatedly rode around the block, then back onto the apartment complex grounds (still screaming/singing). I don't know what ever happened to the police; I never saw them.
I wrote a note about the incident to the manager, dropped it into the office mail slot. (The manager is often gone...very friendly man, but not much of a manager.)

I went to the store, then came back and slept for a while because I was exhausted. Our apartment complex is being painted, so this week has been stressful for everyone, with the painting crew and all the noise. When I awoke from my nap I heard screaming again and discerned that the screaming was coming from inside of the VDG's (Very Disturbed Guy's) apartment. He was yelling so loudly in his apartment that I could hear it inside of my apartment, over the drones of the paint machines and a/c.

As I'm writing this I am not hearing any screaming, but I am a wreck. Seriously. I feel like I'm having a constant mid-level panic attack from all the noise, lack of sleep, and the feeling of knowing that VDG is going to do who-knows-what at any time. I feel very triggered (tremendous fear of violence) and extremely unsafe. If you've read this far I sure do appreciate it, and if you have any idea of what I should or can do - I would appreciate that, too.
