The senior detective leading the investigation into the murder of Lyra McKee in Derry says since her death in the city last week more than 140 people have contacted police with information via the Major Incident Public Portal.
The 29 year old journalist died as a result of injuries sustained when she was shot in Fanad Drive on Thursday night.
Detective Superintendent Jason Murphy said since her death on Thursday evening, the investigation to find her killer is continuing at a rapid pace.
Meanwhile, the New IRA has claimed responsibility for the Lyra's killing.
In a statement given to the Irish News using a recognised code word, the New IRA has offered its "full and sincere apologies" to Lyra's partner, family and friends.
The dissident republican group says she was tragically killed in the course of attacking the enemy.
They say their volunteers were "deployed to engage" after police raided a number of homes on the Creggan estate on Thursday.
In the violence that followed, Lyra McKee was shot while standing beside a police van and later died.
