Detectives hunting the killer of journalist Lyra McKee have released footage of the Londonderry shooting as they appeal for information.
The 29-year-old was struck by a bullet as she was observing rioting in Northern Ireland on Thursday night.
Police have blamed dissident republicans for the murder and believe more than one person was involved.
CCTV captures Ms McKee’s final moments in the crowd and mobile phone footage shows the suspected gunman.
In the video, the masked attacker leans from behind cover and appears to fire shots towards police and onlookers.
