With the start of the summer holidays the police will launch a nation-wide operation aimed at reducing alcohol and drug abuse among minors, a police spokeswoman said on Monday. Over 1,500 police officers are to take part in the operation checking on pubs and restaurants to make sure minors are not served alcohol or allowed into game bars. One of the reasons for the wide-ranging measures is that Czech youngsters top the European ladder in the consumption of alcoholic beverages and cigarettes. In 2015 a similar operation detected 660 children who had been drinking, in 2016 it was 395. Music festivals where alcohol and drugs are also widely available will also be targeted.
