Shops in Accrington are being praised after they refused to sell alcohol to underage drinkers during a crackdown.
A 15-year-old test purchaser was sent into 15 off licences across the town to try and buy alcohol and all refused to sell alcohol to him.
Police, who teamed up with Lancashire County Council’s Trading Standards Department for the operation, have welcomed the result.
Special Inspector Gareth Mead said: "I am very pleased with the results which clearly show that our messages are getting through. Underage drinking is something that we take very seriously and we will continue to run similar operations in the future."
Head of Lancashire County Council's Trading Standards Service, Paul Noone, said: "I would like to praise those retailers who have been diligent and challenged correctly the young people used in this operation.
"Further test purchasing operations will be conducted to test business systems as part of an ongoing programme, and our aim is to ensure that we can replicate similar results to those that have been reported in Accrington."
Councillor Albert Atkinson, deputy leader of Lancashire County Council, said: "The results are encouraging and show that by working in partnership with business we can work to reduce the instances of young people accessing alcohol via retail sale."
The crackdown took place on Friday, November 25.
Police are urging anyone with information about underage drinking or anti social behaviour to contact them on 0845 1 25 35 45.
