A 10-thousand pound sterling reward has been offered for information about the murder of Lyra McKee.
She was shot dead by members of the New IRA in Derry during riots last Thursday.
Her killing has led to new calls for Northern Ireland's political leaders to talk about resuming power sharing.
At Lyra's funeral yesterday, the presiding priest criticised politicians for not yet reaching a settlement.
Talks aimed at restoring power sharing are expected this week between Northern Ireland Secretary Karen Bradley and the Stormont parties - two years after it broke down.
Sinn Fein leader Mary Lou McDonald says the stalemate isn't sustainable: 'The Irish and British governments need to urgently meet. They need to set out and articulate the outstanding equality issues. People now want a resolution'.
