Police in Barnsley are to carry out covert operations looking for pubs, clubs and businesses selling alcohol to underage customers.
Chief Inspector Mark James, of South Yorkshire Police, said: “Selling alcohol to anyone under the age of 18 is not only illegal but could have major repercussions on that person and others in the area too.
“Drinking alcohol lowers your awareness, leaving you more vulnerable, but can also increase antisocial behaviour. We want everyone to be able to enjoy his or her night out and be able to do so safely.
“Enforcing this policy is not only for the safety of these people, but also for the safety of the premises involved.
“Those who are found to be selling alcohol to underage drinkers will face an immediate £90 fine. The business involved and designated supervisor of that establishment will then be put on to an action plan to try and reform and tackle the issue as well as educate sellers.
“If a venue fails spot checks twice within three months, and is found to be selling drink to those under the age of 18, they must either voluntarily close for up to two weeks, or have their licence reviewed.
“We are committed to ensuring those businesses who are selling to underage drinkers face the consequences.
Call South Yorkshire Police on 101 to report those who serve children.
