Child Youth and Family are investigating a video in which a 6-year-old boy is seen drinking from a beer bottle as part of a Neknominate dare.
The video of the boy, posted on Instagram, shows him sculling a drink from a Heineken bottle.
A voice in the background eggs him on: "Keep going, keep going."
A relative of the boy told One News that the contents of the bottle was actually fizzy juice and that the clip was a "piss-take" of the Neknominate social media craze; in which people are nominated to scull an alcohol drink before daring someone else to do the same.
A CYFS spokeswoman said the video was alarming and they were now trying to make contact with the boy's family.
