Garda Commissioner Drew Harris says: "2021 was another challenging, but ultimately rewarding year for An Garda Síochána, as it continued its exceptional response to support national efforts to reduce the spread of Covid-19.
"Following on from the work in the previous year, the organisation’s main priority in 2021 was to support public health measures by providing public reassurance, helping and supporting the most vulnerable in society, and ensuring compliance with public health regulations.
"The tradition of dedication and professionalism in the delivery of community-focused policing was more than evident in how, collectively and individually, the men and women of An Garda Síochána worked tirelessly to keep people safe during a national crisis."
