Boundaries

I have been friends with 2 new people for about a month in a half now. I am questioning the friendship after the 2 people set me up to steal someone's lunch by lying to me and saying it was there's (only one of them actually lied but the other was in on it). The one that lied asked me not to be mad about it (no apology for lying or making me out to be a thief). It angered me when they went through the persons food like it was actually there's after I told them what they did wasn't okay.

I didn't eat it any of it and I've lost trust. Apparently, they ate it later when I wasn't there and apparently it wasn't good because it had gotten cold as they told me the next day.. Is it best to cut this off now? Is this a situation that you would move on from?
