GARDAI have issued an alert ahead of four popular events that are set to kick off this weekend. Cops have confirmed they will be out helping to "keep people safe" as major events kick off across the capital. Thousands of people are set to descend on Phoenix Park when music star Zach Bryan takes over the outdoor venue for three sold-out concerts, starting today. And tomorrow night the sold out ‘Kingfishr’ show will take place at Fairview Park. Four GAA matches are scheduled to take place between Saturday and Sunday afternoon. And the British and Irish Lions v Argentina is also playing at the Aviva Stadium tonight. Gardai have also confirmed that two planned public gathering are expected to take place on Sunday afternoon across Dublin city. As more people are expected into the city this weekend, participants and spectators are encouraged to follow advice and guidance from the Gardai. Public transport network as well as roads in and around the city centre are expected to be busy. In a statement, a Garda spokesperson said: "These events have been carefully planned through by Garda Event Co-Ordination Teams in Dublin to ensure that not only are the events appropriately resourced to protect public safety, but that An Garda Síochána will continue to provide its important day-to-day services to people. "Due to both public gatherings due to take place in Dublin City Centre on Sunday, we advise people to anticipate rolling road closures which will have a likely effect on public transport such as LUAS and Dublin Bus services." Gardai said they will have their full traffic management plan in place to keep the traffic disruption to a minimum. Speaking ahead of this weekend’s events, Assistant Commissioner for Dublin, Paul Cleary said: "This weekend is packed with lots of activity and with the summer weather also looking promising, we look forward to helping to welcome thousands of people into Dublin to make the most of their weekend. "We want you to enjoy yourselves if socialising or attending any one of the exciting sporting and music events happening in the city. "But to please be mindful of others and how your behaviour may impact their experience." He continued: "This summer’s public events would not be able to go ahead were it not for the Gardai that will be working above and beyond this weekend and for the remainder of the summer to keep people safe. "Should you feel unsafe or need our assistance in any way over the weekend, please contact us or stop anyone of us on our high-visibility patrols across the city, and in an emergency or immediate danger always dial 999/112."
