Hello everyone! So I live in a house with 5 other people, we all have our own en-suite bathroom and we share a kitchen. I have been in this house now for nearly 2 years, with 2 other tenants who have been here for around the same time. The rest have come and gone. During this 2 year period, we have been dealing with getting our food stolen from the kitchen counter and the fridge on multiple occasions. we have narrowed it down to one housemate, let's call him D. D has asked us for money in the past as well. D uses other people's washing up liquid, uses other people's condiments from their cupboards, and have stolen a plethora of items from the fridges (such as and not limited to milk, cheese, cured meats, sauces cooked meats, yogurt, desserts, an entire uncooked steak,etc). At one point, 2 amazon parcels were also stolen from the kitchen (it was 2 keyboards and it showed what it was on the cardboard box it was delivered in).

We are renting this house from an agency, the rest of the house mates and myself have sent multiple emails regarding this theft. The agency is not at all helpful (suggestions included label your food and clean up after yourselves and create a cleaning rota?) so completely oblivious to the point about the food theft and gave irrelevant suggestions. I feel silly even typing this because it is just some food, but at this point we are all sick of getting our food stolen. We have already confronted D, he lies as easily as he breathes and denies everything. We have asked him to please ask us and then we would be happy to share if we can, he does not ask and only takes things. Multiple times people have had to order food or go out to buy food because that was all they had to eat and D had eaten it.

Recently we put a very obvious camera in the kitchen and have already seen D steal other people's items. Some context about the camera, it was already discussed among everyone and everyone gave verbal consent, including D, to have a camera. I just wanted to get your thoughts and ideas on how exactly we can get D to leave this house, because even with this video evidence of him stealing other peoples belongings, I dont think the housing agents are going to do anything. I am saying this because another house mate rang them and discussed this current situation, and they said something along the lines of "oh we dont have any escalation processes for that im not sure what we can do to help you".

Additional context: D smokes cannabis in the premises, our housing contract obviously says this is not allowed, I dont think the housing agents know he is doing this. Should we report D to the housing agents? or should we report D to the police?

At this point everyone is really frustrated and annoyed and feeling quite stuck, so what can we do to evict him/ ask him to leave?

I hope this question is okay to post, and thank you so much for taking the time to read it and respond! :)
