"We have a big sharp knife waiting for you and we are still going to get you when it goes dark soon".
These are just some of the harrowing threats sent to a Thornbury elderly couple, who have been subjected to 15 year campaign of terror in their home.
They have endured eggs and glass bottles filled with paint being thrown at their property, on Primrose Drive.
A concrete slab was also thrown through their conservatory window, and their car has been repeatedly scratched.
They have also received terrifying anonymous letters, including one reading: "We are still going to get you when it goes dark soon.
"We no (sic) everything you do and we no (sic) everywhere you go.
"We have a big sharp knife waiting for you and we are still going to get you when it goes dark soon."
Detectives at Avon and Somerset Police are now investigating the abuse.
Officers say the paint attacks, in particular, have left them feeling 'vulnerable' because they are unable to clean up the mess themselves.
Roofing nails have also been scattered on their driveway, and wine bottles thrown into their garden.
The majority of the incidents have happened while the victims have been away.
CCTV cameras have been installed, but the offenders still haven't been caught.
Council officers have also improved lighting on the public footpath which backs on to their property to help catch the thugs.
Thornbury beat manager PC Natalie Jones said: “We know the victims are being specifically targeted as the anonymous letters are personally addressed.
“We also know the incidents are linked as the letters quite clearly make reference to the colour of paint the offender threatens to use next.
“Being victim of one incident of criminal damage is bad enough for any elderly couple but to be subjected to dozens of incidents over more than a decade is quite frankly awful.
“The paint attacks in particular have left them feeling particularly vulnerable as they’re unable to clean the paint themselves and have had to pay for it to be removed while the letters have left them scared to leave their home.
“The stress and anxiety these incidents are causing the victims is something we desperately want to bring an end to and we really need the public’s help to achieve this.
“Have you witnessed any of the incidents?
“Have you ever seen anyone acting suspiciously in the Primrose Drive area?
“Have you ever witnessed anyone pouring paint into glass bottles?
“Any information, no matter how insignificant you think it might be, could help identify whoever is responsible for these shameful incidents so please get in touch if you know or have seen something.”
