Earl Spencer, Princess Diana's brother, has stated that a building at Princess Diana's former home was targeted in a suspected arson attack, according to the British newspaper The Independent.

Firefighters rushed overnight to the scene of a blaze at a farm in the Althorp area, which includes the World Heritage-listed estate where the late Princess of Wales grew up. The Earl shared photos of the massive blaze on social media, saying: "I was shocked to learn that the farm was apparently burned down by arsonists last night." The late princess's younger brother noted that the building was empty at the time, saying: "It's very sad that anyone would think this is funny."

Northamptonshire Police announced Wednesday afternoon that they had begun investigating the fire at the abandoned farmhouse, considering it to be arson. In a statement, the police said: "The fire, which was reported in the early hours of this morning, is believed to be deliberate, but the exact cause is yet to be determined. Given the isolated location of the building, officers would like to hear from anyone who may have noticed any activity near the farmhouse before the fire was discovered."

According to the report, police arrived to find the 18th-century, two-story property "fully engulfed in flames." At the height of the fire, four fire crews used water hoses to contain it and prevent its spread.
