A family from Canada is searching for a London dentist who came to the aid of survivors of the tsunami disaster that hit Asia last December.

Alejandra and Mark Perry, 21 year old daughter Melissa Perry, 20 year old son Lyle Perry and their friend, 22 year old Paul Ladner together with the male dentist known only as Bob started to administer first aid to the injured on Phi Phi Island, Thailand, in an area called Viewpoint on the east side of the Island.

Bob, Melissa, Paul and Lyle became the 'first aid' center for many hundreds of injured people. He is a dentist from London, said to have been travelling with his wife possibly in his thirties, light medium build, of dark complexion and eyes, possibly of Indian descent and around 5'10” in height.

The family say that Bob made a big difference and provided moral support for the three young Canadians, hence their search. Please contact the BDJ on 0207 843 3679 or email a.bajaj@nature.com if you have any information.
