Mr Carruthers asked about previous chainsaw usepublished at 14:34 British Summer Time 6 May
Mr Knox also shows two very short video clips, from which the previous picture had been taken as a still, showing Mr Carruthers cutting at a tree.
"That was you up in a cherry-picker?" Mr Knox asks.
Mr Carruthers replies: "That's correct."
Mr Knox says Mr Carruthers arranged to borrow the cherry-picker from a friend to chop down an ash tree that had a court order requiring it to be felled, which Mr Carruthers confirms.
"This was proper chainsaw work, cutting down a big tree?" Mr Knox asks.
Mr Carruthers says that is correct.
Mr Knox says: "You really couldn't remember this was the time you had been cutting trees down when you gave that account to police?"
Mr Carruthers replies: "No, its just your mind goes blank when you're in a situation like that."
Mr Knox says: "You were deliberately trying to give police a false impression weren't you?"
"Not at all," Mr Carruthers replies.
