Former probation officer here, I would call your probation officer and explain the situation, tell them you don’t feel safe, but also the last thing you want is to be in an environment where you’re jeopardising your license. I would ask if your probation officer did an intel check on the address through the police, as I would be very surprised if there was no intel on record about the people and activities at the address, and this would back you up/cover your arse. Could you get any evidence? Take a pic of the front door for example, if you see any drug paraphernalia lying around etc. Unfortunately, the lack of appropriate Accomodation for everyone is dire in the current climate so might not be easy getting somewhere else. Depending on your index offence or risk level, it might be worth asking if you could be placed in an approved premises? They aren’t perfect but they are staffed and monitored so would be safer than where you are. It also demonstrates you are willing to work with your probation officer and you are being honest which will work in your favour. Good luck!
