A man arrested under the Terrorism Act by police investigating the murder of Lyra McKee has been released.
The 46-year-old was arrested after the PSNI carried out searches at properties in the Northland Road and Creggan areas of Londonderry.
He was taken to Musgrave Serious Crime Suite for questioning before being released without charge on Thursday evening.
A number of items were also seized and taken for further examination during the police searches.
Detective Superintendent Jason Murphy said: “Since Lyra was murdered following violent disorder in Creggan in Derry/Londonderry on April 18, our investigation has received widespread support from the community.
“I still want to hear from anyone who has any information and would appeal to the public to contact my team of detectives on 101. Alternatively, if you would prefer to provide information without giving your details, you can contact the independent charity Crimestoppers and speak to them anonymously on 0800 555 111.”
The journalist was shot in the head during rioting in the Creggan area when a gunman opened fire on police in April.
Police have said they believe dissident republican group the New IRA were behind the attack.
The group have since admitted responsibility for the murder of the 29-year-old.
