Hmmmm . ........ were they caught stealing a CCTV camera, then?
Surely the meaning is "....... caught by a CCTV camera......" ?
Is there a difference between the two in Welsh, or is it just in English?
Ha! Yes, you're right! "by" would be "gan". This sentence implies that they stole a CCTV camera (which is quite possible if they're relations to the Lingo family!) :P
does 'gyda' also work here or must it be 'efo'?
We have "caught ON (a) CCTV camera", like you see something ON (a) television.
