Lafayette Park-Stockwell Place

I moved to the Stockwell Place neighborhood a year ago. There are new neighbors across the street that have an 18 year old son who has been in trouble with the law, has made some questionable comments to people on the street and just today got into 2 arguements with 2 different neighbors, and made an indirect threat to another neighbor. Can someone please tell me if Stockwell Place has a HOA and how do I get in contact with them. I want to know the rules on an unruly neighbor. I am going to start a paper trail  by calling Bossier PD everytime in case there could be an incident in the future.
