From 10.00pm last night it started, we didn't know where it was coming from but it was pretty loud, I thought it would probably go off after half hour but no all thro the bloody night, in the end I rang 101 and they told me that they needed a house number in order to inform the council (i had to resort to an earplug) so 8.00am this morning I call the council, they eventually got it off at 1.00pm today.
