Dublin Fire Brigade says it received more than 200 Halloween-related fire calls yesterday.
A number of anti-social behaviour incidents were also reported around the city, although the fire service said that they are actually decreasing.
And that is a wrap on our #DFBLive Map. We'll update it in the morning with any fires that happen after midnight. The good news is that the majority of fires are now either out or died down, however if you have concerns ring us on 999 or 112— Dublin Fire Brigade (@DubFireBrigade) November 1, 2018

On Captains Avenue in Crumlin, three cars were set alight at around 8pm.
In Leinster, fire services recorded more than 900 calls last night, most of which were Halloween-related.
Acting Assistant Chief Fire Officer with Dublin Fire Brigade, Greg O'Dwyer, said 368 of the calls were bonfire-related, and another 365 were ambulance calls to deal with injuries to hands and eyes.
A positive for the fire service was that organised events by local authorities and a garda clamp-down on the collection of items for bonfires this year have seen a fall in the number of injuries.
In Cork, there was a modest number of bonfire-related calls reported, with Cork City Fire Service saying last night was no busier than any other night.
