A MAN has been arrested by police investigating the murder of journalist Lyra McKee.

McKee was shot by dissident republicans in Derry in April 2019 as she observed rioting in the Creggan area of the city. Extremist group the New IRA was responsible for the murder.

The suspect, 27, was detained in Derry this morning under the provisions of the Terrorism Act.

He has been taken to Musgrave police station in Belfast for questioning. Officers also conducted a search of a house in Derry.

Last month, police found the handgun used to kill McKee.

The Hammerli X-Esse .22 pistol was discovered during searches in the Ballymagroarty area of Derry.

In February, a 52-year-old man appeared in court in the city charged with the author's murder. He denies the charge.
