Employees at a southwest grocery store discovered more metal pins in products for sale yesterday morning after sweeping the store just the night before.

Oakridge Centre Calgary Co-Op employees scanned the store yesterday morning before the store opened after the store was closed for several hours Monday night.

“The employees conducted another check before the store opened and that’s when they found pins pushed into plastic juice bottles,” spokesperson Sarah Boutron said.

The store was scanned Monday night after first discovering pins in bakery and bulk items.

Co-Op is allowing customers to return items they bought over the last several days.

“We did have some customers bring items back because they are concerned, and we are totally understanding of that. We’re very thankful for their patience.”

The Calgary police service confirmed they are investigating the incidents but couldn’t disclose details for investigative reasons.
