Detectives investigating the murder of Northern Irish journalist Lyra Mackie have arrested four people.
The men, aged 19, 20, 21 and 33, were detained under the Terrorism Act in Derry on Wednesday morning.
The four have been taken to the Serious Crime Suites at the Musgrave police station in Belfast for interviews.
Ms Mackie, 27, was shot dead by disgruntled Republicans in April after she witnessed a riot in the city’s Cregan area.
The extremist group that styles itself the New IRA was responsible for the murder.
Detective Superintendent Jason Murphy of the Northern Ireland Police Service said: “These arrests are the culmination of an extensive two-year investigation into the murder of Lyra and the events that preceded it.
“The local community has supported the Police Service of Northern Ireland during this lengthy investigation and I would like to thank them for their continued support and patience as this phase of the investigation continues.”
Paul McIntyre, 53, of Kinnego Park, Derry, has already been charged with the murder of Ms. Mackie.
Another man has been charged with rioting and other crimes related to the events of the night at Cregan.
Mackie, a rising star in the world of journalism, covered communalism extensively in her short career.
His work has appeared in several publications, including Granthshala.
Mackie was also a prominent gay rights activist and campaigned for greater equality for same-sex couples in Northern Ireland.
