A man and two women in Derry have been charged with the possession of firearms with intent to endanger life.
The charges relate to a police operation on the city's Letterkenny Road on Friday in which two handguns were found in a car.
A fourth man arrested in the operation has been released without charge pending a police report, a PSNI spokeswoman said.
The other three are due before Derry Magistrates Court at 10.30 tomorrow morning.
