This is the shocking moment a young boy downed a pint of Guinness as two men egged him on.
The mobile phone footage, reportedly filmed in a noisy pub in Ireland, shows the boy playing with a plastic car before picking up a pint of what appears to be Guinness.
The youngster, who looks around five years old, then proceeds to drink the pint, seeing it off in less than 50 seconds as the men cheer, the MailOnline reported.
As he drinks, two men around him egg him on. They can be heard saying: "Go on, keep it going. Fair play to you boy".
The men tell the boy "go on, you have it... tip the glass... go on son... all the way".
A Gardai spokesman said: "Garda Siochana are aware of a video which shows a young child drinking alcohol.
"The video is currently on various social media websites. The Garda National Protective Services Bureau are currently investigating this matter to establish the full facts."
