"We concluded that the ad breached the code and we welcomed Heineken's confirmation that it had already been removed."
Alcohol Concern's head of policy Tom Smith said: "Not only is it appalling that a company such as Heineken UK, with a marketing budget of millions, is failing to comply with the advertising codes, but it's left to young people to spot these adverts and highlight these failings.
"These big companies clearly can't be trusted, so to better protect children and tackle patterns of alcohol harm we need urgent reform of the alcohol advertising regime."
