Dark patch on eye iris

Man in a Shed and his wife have been horrified by the abduction of Madeleine McCann. On of the best ways to identify her is a dark patch on her right iris below the pupil. Hopefully even in years to come this will still allow her to be identified. She was 4 years old in May 2007 - anyone having information should contact the police:

Portuguese Police direct on 00351 282 405 400
or call UK Crimestoppers on 0800 555 111, +44800 555 111 outside the UK I assume.
