Reward offered for information about Philip Cairns

Crimestoppers is offering a €10,000 reward for information about the disappearance of a Dublin schoolboy 21 years ago.

Thirteen-year-old Philip Cairns disappeared while walking to school in the Rathfarnham area in October 1986.

His schoolbag was found in a laneway near his home a week after the disappearance.

His pens and pencil case were still in the bag, but two books were missing and gardaí believe the bag had only been in the laneway for a short time before it was discovered.

In recent months, more than 50 people have come forward to provide new lines of inquiry to investigating detectives.
