Police arrested two teenagers of the age Eighteen and Nineteen, for kiiling Lyra McKee.The both are arrested under the terrorism act.
They killed Ms McKee while she was covering the rioting in Londonderry in Northern Ireland on Thursday night.
It happened in the Creggan estate. Violence broke out after raids in the nationalist Mulroy Park and Galliagh areas by police investigating dissident republican activity.
Ms McKee was standing near a police 4×4 vehicle with other journalists when she was shot.
CCTV captured her final moments in the crowd and mobile phone footage showed the suspected gunman.
The Police Service of Northern Ireland (PSNI) said a gunman fired shots towards police officers at about 23:00 BST on Thursday.
In the video, the masked attacker leans from behind cover and appears to fire shots towards police and onlookers.
There has been widespread condemnation of the killing.
PSNI Det Supt Jason Murphy, who is leading the investigation, described Ms McKee’s death as “senseless and appalling beyond belief”.
At a vigil in Derry on Friday, Ms McKee’s partner, Sara Canning, described her as a “tireless advocate and activist” for the LGBT community.
Ms Canning said her partner’s dreams had been “snuffed out by a single barbaric act” and she had been left without “the woman I was planning to grow old with”.
“The senseless murder of Lyra McKee has left a family without a beloved daughter, a sister, an aunt and a great-aunt; so many friends without their confidante,” added Ms Canning.
“We are all poorer for the loss of Lyra.”
Ms McKee’s killing came 21 years after the Good Friday peace agreement was signed in Northern Ireland.
The 1998 peace deal marked the end in the region of decades of violent conflict – known as the Troubles – involving republicans and loyalists during which about 3,600 people are estimated to have died.
The Good Friday Agreement was the result of intense negotiations involving the UK and Irish governments and Northern Ireland’s political parties.
Figures from across the political divide, including Sinn Féin leader Mary Lou McDonald and DUP leader Arlene Foster, were among the hundreds of people to attend the vigil.
ne of Ms McKee’s close friends, Kathleen Bradley, told the BBC: “Lyra was a voice – she wasn’t afraid to stand up and hold her view.
“Lyra managed to get Mary Lou McDonald and Arlene Foster into Creggan [for the vigil] without any high security or barricades.
