Customs officers on Friday issued a warning about a stress-relieving toy that comes with a syringe, urging shops to remove the item from their shelves immediately.

Officers said the toy could hurt children and parents should stop their kids from playing with it right away.

In a statement, authorities said they inspected toy shops across Hong Kong after receiving a complaint, but have not found anything so far.

"Customs will continue to closely monitor the market situation and step up patrols. If found, the department will take resolute enforcement action," the statement read.

A video circulating online shows a person using a syringe to inflate a mini baby doll, creating a bubble effect.
