A man has been charged with the murder of journalist Lyra McKee.
Ms McKee was shot dead in the Creggan area of Derry city on April 18 as she observed rioting.
A spokesperson for the Police Service of Northern Ireland 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 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. "
Detective Superintendent Jason Murphy said that the investigation is ongoing.
"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," he said.
Three other men who were arrested in connection with the investigation have been released.
A 29-year-old man was released without charge earlier this afternoon.
Two others, aged 20 and 27, who were also arrested in Derry on Monday, were released pending a report to the Public Prosecution Service.
