A total of 405 Penalty Notices for Disorder (PNDs) were issued to young people in 2013/2014.Area Commander Chief Inspector Jon Burrows said: "There is a range of disposals for anti-social behaviour. In the most serious of cases we will prosecute. However, we recognise that a conviction for disorderly behaviour can impair the future of young people, and we have other disposals, which includes Penalty Notices for Disorder (PNDs)."He continued: "It is the police working in partnership that makes communities safer and not the so-called vigilantes who only succeed in brutalising young people and damaging confidence in our city."Meanwhile, the number of anti-social behaviour incidents reported to the PSNI in Foyle dropped by almost 900 in the last financial year.Chief Inspector Burrows said that this was the largest decrease of any policing area in Northern Ireland, representing a fall of 16.3 per cent.I am under no illusions that anti-social behaviour is regarded by many as a scourge.Chief Inspector Jon BurrowsIn the last 12 months, 4,571 incidents have been reported while in 2012/13, the number stood at 5,462."The huge reduction in anti-social behaviour will make a difference to communities right across this city and we will continue to work in partnership to reduce crime and make people safer."This demonstrates our commitment to neighbourhood policing, partnership and community priorities. We have worked hard not only to proactively patrol areas, but to bring communities along with us and encourage them to sign up to initiatives that tackle the root causes of anti-social behaviour."It takes many shapes. It can range from young people playing noisily with a ball close to the homes of elderly people, to alcoholic-fuelled parties that lead to disturbances," he explained."We believe that people having consideration for others is crucial. That is why we encourage people from differing backgrounds to get together, and encourage community and social groups to provide alternative outlets. Our neighbourhood officers are in schools right across the city talking to children and young people about good citizenship, respect and their personal safety."
