Officers from Norfolk Constabulary have praised thousands of people across the county who celebrated Halloween last night as reports of anti-social behaviour across the county fall for the fifth year.

Additional officers were on duty across the county for what can be one of the busiest nights in the policing calendar.

Norfolk Police received around 55 calls related to Halloween on October 31. This continues trend of a reduction in calls over Halloween that Norfolk has seen over the past few years, with 70 received in 2012, 82 in 2011 and 2010 and 98 in 2009. An incident in Wymondham saw a special police constable suffer a minor injury after a firework was thrown into an alleyway.

Inspector Paul Garrard, from the Operational Partnerships Team explained: 'The evening passed without major incident and I would like to thank trick or treaters for showing respect to those who did not wish to take part in the celebrations.

'We have worked with residents, partner agencies and local businesses to support vulnerable people over Halloween and passing on advice on enjoying the festivities safely. I'd like to remind residents and reassure people that Safer Neighbourhood Teams will again be continuing this presence out in their local communities for Bonfire Night celebrations and in the night time economy to ensure this continues.'

The run up to Halloween saw a range of engagement activities as part of the national Association of Chief Police Officers (ACPO) 'In Focus: ASB' week of action to highlight the kind of anti-social behaviour (ASB) which can be seen during Halloween and the effect this can have on our communities and more vulnerable residents.

Assistant Chief Constable Nick Dean, explained: 'Our activity across the county this week was designed to raise awareness of what constitutes ASB and what we as a constabulary are doing to tackle it.

'It is pleasing to see that once again this year reports of ASB, at one of the busiest times of the policing year, have fallen. This shows our increased police presence in hotspot areas and engagement with local communities has a real impact.'

South Norfolk PCSOs supported a community led initiative helping to handing out hotdogs and hot chocolate on Halloween in a bid to reduce the level of ASB and engage with young people.
