Two police officers are being investigated after they filmed a video near the site of the Shoreham air show crash and captioned it with an "offensive and inappropriate" comment before sending it to colleagues.
Sussex Police are looking into the alleged misconduct of the two officers, who recorded a video of themselves stood at a cordon "some distance" from the scene of the fatal crash on August 22, which claimed the lives of 11 people.
Deputy Chief Constable Olivia Pinkney said that the video, which was reported to management by one of the recipients of the message, did not show anything explicit from the crash, but did have a concerning caption attached.
DCC Pinkney said: "I am so upset that two officers have so badly let down the 11 families of those who died at Shoreham air crash and have let down hundreds of their colleagues who have also been working so tirelessly since that day."
She added: "What the two officers did was record a video of themselves when they were on duty standing at the cordon, some distance from the scene and without anything showing, but it had attached to it an offensive and inappropriate comment."
The two officers have not been suspended, but are not working in contact with the public, said DCC Pinkney.
Eleven people died when a vintage Hawker Hunter jet plummeted on to the A27 in West Sussex during its display at the Shoreham Airshow last month.
