Four men have been arrested by police investigating the murder of Lyra McKee.
The journalist died after she was shot in the Creggan area of Derry last April.
The PSNI arrested the men under the Terrorism Act after the New IRA claimed responsibility for her murder.
Three of the men arrested are in their twenties and one is in his early fifties.
All four men have been taken to the Musgrave Serious Crime Suite in Belfast.
