Skateboard might be stolen by housemates?

So on friday I went to the shops with my board. Came back and put my board back next to the front door like i always do.

My female housemate had a male friend over. She's French Algerian and works full time as a cook. But I've only known her about a month and she's leaving in a week. And I've never seen her friend before. Looked a bit sketchy.

On saturday I go to grab my board for a skate and it's gone.

There's two possibilities here:

a) I left the board at coles when i was doing a shop. (already checked their lost p;roperty, no luck).
b) This friend of my housemate has taken it.

I think my apartment manager keeps security tapes but he's on holiday atm.

Should I confront my housemate about it? Or just wait for my manager to return?

What should I do, skaters? It was a sweet board with ceramic bearings.

Where do you live?
What board, trucks, wheels, etc? Pics?

Re what should you do?

Definitely make some comment about it, without actually asking directly did you or your mate take my board.

Everyone can keep an eye out for it as well as you maybe doing some checking with simple questions about her mate, seeing him again, where he lives, etc.

Got to deal with that, however you can.

Surely you can remember if you skated back from the shops or walked? Fair difference...
