PROF DE KOKER
That would be a correct interpretation of this first sentence but unfortunately, then it goes on to say
"I did in fact to what I was instructed to do, I threw the hand grenade towards the door at the Trust Bank building"
And as far as I know, there's only one Trust Bank building in Kimberley.
"I threw it towards the door of the Trust Bank building where the Bophuthatswana Representative and Mr Uys were standing"
	He therefore identifies the particular building and then said he threw it towards the door of this particular building where the Bophuthatswana Representative and Mr Uys were standing.
