Is there actually any evidence that this dog ever got anywhere near Bamber? And if it did, why did the defence not mention this at trial as Bamber surely would have remembered a close encounter of the canine kind?
Yes, there is Vic, I've just found it.
From PC Dermott's statement
"After a few minutes I was called up to the building via green side where I met with Ps Adams and Jeremy Bamber in the cattle shed on white/green corner. Ps Adams instructed me to wait with Jeremy Bamber whilst he went to speak to Pcs Collins and Delgado. Whilst I was there I had another conversation with Jeremy Bamber...
Ps Adams asked for a dog handler to join my position and we were joined by PC Mercer. I was instructed to find a containment postion on black side and I took PC Mercer back to our transit and equipped him with body armour. We then went to the black side of the building and were unable to find a containment postion because of the density of the hedgerow.
PC Mercer and myself ended up by a barn on black green corner...
Prior to the entry to the building PC Mercer was relieved."
So dog handler PC Mercer [and his dog, or why ask for a dog handler?] were in the cattle shed on white/green corner with Jeremy Bamber.
