The Clown in the woods

So i am a police officer well Special constable to be truthful but what i saw in the woods will ok might stay with me for life.
I was working the night shift 2 nights ago downtown in the city centre ok for a Friday night it was bad members of the public getting drunk and also starting fights after the bars had closed i had only just gotten back out of the station after taking a young male around the age of 16 and who had been under age drinking.
after taking him to the station and getting back on patrol after doing the paper work on him it was a good 2 and half hours after getting back out and nothing happing i got a call from control telling me that there was a 999 call and the caller said the was in the woods i wont say the name of the woods.
but when i got their and cut off my sirens but kept my blue emergency lights on and flashing along with me head lights on and getting to the end of the woods where a building was.
after getting to the end of the woods where a building was and not seeing anyone i contacted my the control room and telling them that it might just be a prank call by youths and was going to check the building out and if needed stay with them until their mother and father/ career comes back and tell them why i am their.
as soon as i got out of my car and only being crewed alone so not have any back up to help me.
when i got out of my car and walked up to the door i noticed they was a song coming from within the building along with laughing i knocked on the door and someone turning down the song the door slowly opened when i went into the building in question and checked every where and not seeing anyone well that’s when i was about to leave the building that’s when i saw around 9 to 10 people dressed up as clowns but was only at the back door and all holding hunting knifes.
this being England and me not able to carry and weapon on my parson and seeing them all have knifes i ran to my car all the while reaching for my radio emergency button on top and getting no response from the control room back at HQ but being able to get inside my car and revers out of the wood i drove away still trying to reach help when i remembered my phone i called 999 and told the operator who i was when she put me thou to police and the control room asking why i wasn’t answering my radio .
before i could explain i heard a explosion and saw smoke and fire coming from the woods when i told control what had just happened they told me to keep everyone back and the fire services are on their way as we speak.
after the fire service put the fire out and i went to see for myself i saw the building the clowns was in and a little note the note read HAPPY HALLOWEEN PIG signed ~killer Miller~ .
so clowns we will be looking out for you this time.
