A routine walk turned into a curious event for TikTok user 'alastairmoss' and his son when they heard a loud, eerie air raid siren echoing through the streets of Maidstone, Kent.

Just as they were about to enter their house, the unusual noise drew them and several neighbors outside, all equally puzzled. Speculation abounds as to the cause—some suggest it was an air raid test, while others believe it might be linked to a nearby festival.

I was going for a walk with my son and was just about to walk in the house when we heard this very eerie air raid siren going off very loudly! Lots of other people in the street came out just as inquisitive as us! There’s lots of speculation as to what it actually was, some people say air raid testing others say a festival, you decide!
