BURLINGTON — A giant, decorative concrete ball was a rolling stone Wednesday after it broke free from the sidewalk outside a mall and struck a car.

Several of these balls adorn an entrance at Mapleview mall in Burlington where Halton police confirm the incident happened.

Mapleview general manager Rita Donnelly said the "unfortunate event" happened after an SUV struck the bollard.

"We will be taking the appropriate measures to ensure that this type of incident does not occur again," she said in an emailed statement Thursday.
