Ask the Police (UK): Website and app information resource containing answers to a wide variety of the general public’s most frequently asked policing questions. “The website provides links to relevant national organisations plus the facility to rate the answer and email a specific question directly which will be answered within 24 working hours. Police forces are able to input additional local police information and advice for the benefit of their communities.” (Source: https://firstname.lastname@example.org).

The most regular Twitter hour is with the Chief Constable @ChiefConPSNI, using the hashtag #AskChiefCon. These are run twice a year. Other command teams at District Level also run their own twitter hours.
