Three girls left alone with another sibling in an abandoned house have been gifted with birthday presents and cake by the same police department responsible for their discovery.

In a post to its Facebook page earlier this week, the Chicago Police Department described how officers found the girls, aged one, two and seven, alone without a guardian.

After taking the girls to hospital for a general check-up, police had them relocated to the care of their grandmother.

While the woman was “very willing” to take her children in, the post said she was faced with “limited resources” due to unemployment.

Moved by the plight of the three girls, members of the police department have since made multiple visits to the grandmother’s house bearing gifts of clothes, food, toys, diapers, and furniture.

All of these goods have reportedly come from the officer’s own homes or were purchased out of pocket.

Upon learning two of the girls happened to have a birthday on the same week, the officers threw an “impromptu birthday party”, complete with presents, cake and ice cream.

The department has celebrated the act, remarking that such “compassion and generosity…is rarely captured”.

The post is accompanied by photos of the grandmother and her grandchildren enjoying the gifts and cake.
