There has been a lot of debate on this subject. Whether he was retired from the police force and employed by the police, to use his dogs in Playa da luz, or whether he was still being paid as a police office/dog handler is still unclear, but it makes little difference really, does it?
Martin Grime was not a serving police officer when working in Praia Da Luz and although retaining his expert accreditation it is interesting to note that his dog did not.
That he was retired, explains why he was not in uniform when working, unlike the officers who took part in the most recent dog searches in PDL. He was there in a private capacity although someone must have contracted him for the job, whether that was Leicestershire police or the Portuguese authorities ... who knows ... but someone lifted the bill and as a private contractor he would be paid for his work.
I think concerns could legitimately be raised at the elapse of time between Madeleine's disappearance and the deployment of a VRD.
One wonders about the difference in cost, if any, of using a contractor and his dog and using a police dog team.

Martin GRIME was an ACPO accredited dog handler whilst he was a
serving police officer, but forfeited accreditation upon his retirement in
July 2007. We mentioned that Mr GRIME remains on the ACPO
accredited list of experts though his EVRD is no longer accredited by
ACPO.
