did citi just buy more shares?, page-4

It's not legal if Citi were/are acting as a nomineee holder for BHP.

I suspected something fishy was going on post placement to CRM. The selling was relentless.

Now we know why.

Question is do Citi have a relationship with BHP to act as their nominee?

In my opinion, the purely circumstantial evidence gives the appearance that they most cirtainly do otherwise why would they sell it down to 90c only to buy back at %1.26?

If you watched the tape post the CRM transaction you would have noticed UMC dropped 50c under the CRM placement. Not enitirely normal trading behaviour for such an importmant announcement.
