Police Sergeant Whelan found nothing suspicious about the mass grave of 800 children.

(CNN) -- Outrage over the reported discovery of the bodies of almost 800 children at a former home for unmarried mothers run by nuns in Ireland prompted calls Wednesday for a full investigation.

The children whose remains have apparently been found in Tuam, in County Galway, are believed to have died between 1925 and 1961, according to local media reports.

The grim discovery was highlighted in a front-page report in the Irish Mail on Sunday, which cited the efforts of local historian Catherine Corless to research the burial sites of 796 children listed as having died at the home, which was run by the Sisters of Bon Secours.

According to the newspaper, Corless believes their remains are all buried in the unmarked mass grave next to the place where the home once stood. Local children stumbled upon the grave in the 1970s, local media reported, but the site was never examined afterward.

The revelation has sparked calls for an investigation and renewed questions about the treatment of unmarried mothers and their children by the Catholic Church and institutions associated with it.

Sgt. Brian Whelan, in the press office of Garda, Ireland's national police, told CNN there was nothing to suggest any impropriety and that police are not investigating the matter.
