Evolv Technology has been asked to change claims its technology has been tested by the government.
Evolv Technology makes "intelligent" scanners designed to replace metal detectors by identifying people with concealed guns, knives and bombs.
But the company has come under mounting criticism for overstating what the technology can deliver.
Evolv told BBC News it had altered its claims about UK testing to "better reflect the process taken".
This is a Theranos level of fake it till you make it: lie about where the product is used, who approves it and how well it works and hope the reality catches up quicker than clients.
It's pretty clear the technology is not ready for this, and once again regulators and prosecutors won't move a finger to prevent potential harm.
