I doubt she was under house arrest as such. But the access card issue does come up when people sub rent an apartment.
A 2 bedroom apartment with 2 registered tenants usually gets 2 access cards.
The police can (and will) go through old CCTV recordings to see if the "scarf as a
door wedge" was a common occurrence. A lot of things that strike as strange to us might have been totally normal and routine to others.
I imagine the brother would have one card on him, and the other one would have been with the father/Amesha. Didn't sound like the father was planning to go out ... Wonder why Amesha didn't take an access card, if she was just ducking out to buy milk and butter.
Then again, the whole timing of the saga sounds a little odd. Why not buy milk and butter earlier in the day, or wait until the next day? Or, as others suggested, ask the brother to get some on his way home?
Sounds like she could have been using that as an excuse to get out, like she needed or wanted to go out for a bit. Did she sense someone was coming over to try and meet up with her for whatever reason??
And, of all times, those phone calls from the brother. Why did he want to speak to Amesha, I wonder? It sounded like he wanted to speak to her quite urgently, but nowhere is it disclosed, what he wanted to speak to her about, despite there being quite detailed reports about the takeaway, gift cards etc.
It could have been, that he was trying to warn her about someone or something?? Maybe the father was not aware of something the brother was aware of?
And the father answering her phone/her not taking her phone with her. Did kind of strike me as him being the 'keeper' of that phone. But, who knows, perhaps it was the only phone left in the unit... They may not have a landline and the father may not have his own mobile....
Just goes to show that, on reflection, most things can be seen in more than one way, with so little information.
Hope we hear something soon!
