A family lost treasured sentimental items in an arson attack on Monday.
Everything in an outhouse in Oldham Drive, Pinchbeck, was lost in a fire started at around 6pm.
Jarred Farmer, son of homeowners Julia and Jason Farmer, said photos and sentimental reminders of his grandparents had been destroyed.
He added: “We had another house fire in 2011. Everything we managed to keep, we put in there.
“It’s a really upsetting time, especially when you know it was arson.”
Anyone with information should call police on 101 or Crimestoppers anonymously.
