Police in Northern Ireland on Sunday released without charge two young men arrested in the investigation into the death of journalist Lyra McKee during riots in Londonderry. 
McKee, 29, an award-winning journalist who was writing a book on the disappearance of young people during decades of violence in Northern Ireland, was shot in the head late Thursday as she watched Irish nationalists youths attack police following a raid.
The two, aged 18 and 19, had been arrested under anti-terror laws and taken to Belfast for questioning.
Announcing their release, the Police Service of Northern Ireland made a fresh appeal for witnesses who saw what happened on Thursday night to come forward.
"I know there will be some people who know what happened but are scared to come forward but if you have information, no matter how small, please contact detectives," Detective Superintendent Jason Murphy said in a statement.
