Bottom floor neighbour propping front door open throughout day and overnight

As in the title, we’ve got a particularly difficult neighbour propping the communal close door to our tenement open. She says it’s because her cats need to come in and out, but she also has people come throughout the night. No idea why or who they are.

I’d say she very likely has some personality issues and is generally incredibly angry and aggressive. We’ve attempted multiple times to intervene and politely request she keeps the door closed at night. However, unfortunately she will not listen to any reason and usually ends up shouting and (sometimes) threatening whoever asks her to keep the door closed. It’s gotten pretty bad now- there were 4 random people in our close two days ago smoking and shooting up because the door was left open.

The police were called a couple nights back as she got into an argument with a neighbour at 2am and called the police herself. Unfortunately, she owns her flat. We feel were in a bit of a bind here as she is on the bottom floor- we continue to dispose of anything she uses to prop the door up, but she just gets something else and then shouts and slams her door each time she does this.

I’m sure others in Glasgow have experienced similar things - wondering what others have done? Any thoughts welcome.

Edited to add that she hasn’t paid factor fees in years. Myself and other homeowners were given 5k of her debt just last month.
