With this year's Halloween celebrations in Londonderry underway, local PSNI have been raising awareness about anti-social behaviour in the city.
The festival started this weekend, and will continue until Tuesday evening, concluding with the Halloween street carnival parade and fireworks display.
Around 80,000 people were in attendance last year, and earlier this month the New York Times listed Derry as one of the world's leading Halloween destinations.
The seasonal festivities bring an increase in the number of police call-outs for anti-social behaviour, and on its Facebook page PSNI Foyle has listed a number of incidents from last year in an effort to raise awareness.
One call-out received by police was from a woman complaining a large party was taking place at her neighbour's house.
The report listed on the PSNI's Facebook page reads: "10.05pm: Caller reports a large party next door and some of the partygoers are urinating in her garden."
One woman called the PSNI after eggs were thrown at her home, thinking someone might still be in her garden.
Writing on the PSNI Foyle Facebook page, a spokesperson said: "On the face of it, you might think a few eggs being thrown is harmless but I'm pretty sure the people responsible for this call didn’t think about the impact it had on the lady living here.
"It’s dark; she can hear noises in her garden and the sound of something striking her front door and windows. She doesn’t know who is out there and she feels scared in her own home."
Once incident saw fireworks thrown inside a shop while customers and staff were present.
A PSNI spokesperson said: "Setting off a firework in an enclosed space is madness. Fireworks are explosives and there is no telling what damage they can cause to either people or property when not handled correctly. Thankfully no one was hurt during this incident but the risks are real."
In another incident a large group of youths who appeared to be under-18 were reported drinking outside a shop.
"First of all the behaviour of these young people was causing annoyance to shoppers and staff. More importantly, the young people were putting themselves at risk," a PSNI spokesperson said.
