A 52-year-old man has been charged with the murder of journalist Lyra McKee.
The 29-year-old journalist was shot dead as she observed rioting in Londonderry on April 18 last year.
The New IRA said it carried out the killing.
A PSNI statement said: "Detectives from the PSNI's Major Investigation Team have charged a 52-year-old man with the murder of 29-year-old journalist Lyra McKee, who was shot dead by terrorists in Derry/Londonderry on 18 April 2019.
"The man, from the city who was arrested by detectives yesterday and taken to Musgrave Serious Crime Suite, is also charged with possession of a firearm with intent to endanger life and professing to be a member of a proscribed organisation. He will appear at Londonderry Magistrates Court on Thursday, 13 February. "
Ms McKee was standing near a police vehicle when she was hit by a bullet fired by a masked gunman towards officers.
Detective Superintendent Jason Murphy said: "I have always said a number of individuals were involved with the gunman on the night Lyra was killed, and while today is significant for the investigation the quest for the evidence to bring the gunman to justice remains active and ongoing."
