Advice after upstairs neighbour arrested at 4am by 5 police officers

[Lulabelle25]

I'm worried about my security and safety after 5 police officers came to the house at 4am and arrested a man living in the flat of my upstairs neighbour . Before they took him away i heared them say it was for failing to attend court. My neighbour herself tried to assault me last year and I do not even know if the housing association know the man who was arrested yesterday is living there. My neighbour and i share a front door on a street property. What can I do to ensure my safety and security now?

This is nothing to do with you.
He could have not turned up to court over something minor. Police could have just tried their luck seeing if he was in and he opened the door.
Doesn't make him a serial killer

And the HA won't do anything, I have a nasty male who lives upstairs threatened to hit me on camera and police did nothing, the HA gave him a warning. I'm a woman living alone. The fact I complained made it worse.
I'm now looking to move I suggest you do as well especially as you share a front door that is horrible

And back in the real world ….

you really think OP wouldn’t have already done this if she could??

And in my experience, the housing association sought a closure order and the people who had been making everyone's life a misery were evicted.

It's fucking scary being a lone woman and hearing violence, wondering if the next boot is going through your door or if someone is going to mix up your address with the druggie they're looking for and out your windows through.
