The Press Complaints Commission is investigating a splash that appeared in the Scottish edition of the Sunday Express.
The article, headlined “Anniversary shame of Dunblane: internet boasts of sex, drink and violence as youngsters hit 18”, appeared on March 8.
It claimed a number of those who witnessed the Dunblane massacre had “posted shocking blogs and photographs of themselves on the internet, 13 years after being sheltered from public view in the aftermath of the atrocity”.
A PCC spokesman told Media Guardian it had received more than 30 complaints, two from people the story mentioned.
It has launched an investigation under sections one and three of the editors’ code, which cover breaches of privacy and accuracy.
The story has been removed from the Sunday Express website.
