Two Brighton and Hove police officers are being investigated over a selfie they took at the site of the Shoreham airshow crash.
They sent the selfie to a colleague who contacted the Sussex Police Professional Standards Department.
The pair are now under investigation for gross misconduct.
Deputy Chief Constable Olivia Pinkney said: “I cannot emphasise how upset I am that we are investigating such an allegation.
“My colleagues have informed the victims’ families and apologised to them for the unnecessary distress it will undoubtedly cause them.
“They are disappointed as we all are. Such an allegation impacts on everyone who was affected by the crash and detracts from the professionalism of hundreds of colleagues who have worked so tirelessly on this operation.”
“All our efforts are focused on providing the families with the answers they are looking for.
“I encourage my officers and staff to report any alleged behaviour that is below the standard expected, and that is what has happened here. We need to follow processes in relation to disciplinary matters.
“The officers, who are quite new in service, have not been suspended as I want them to work to earn their pay while this is investigated. In the meantime they have been assigned duties away from public contact.”
Eleven people died in the crash when a Hawker Hunter jet failed to complete a loop the loop on Saturday 22 August.
