Arrest after suspect devices found outside Londonderry homes
Police say the security alerts are not linked to terrorism or the murder of Lyra McKee
A man has been arrested after two suspect devices were found outside houses in Derry on Sunday morning.
Residents in several properties were evacuated while an area close to the city's police station on Strand Road was among those affected by the disruption.
The 39-year-old suspect was detained in the city and taken to a Belfast police station for questioning.
A police spokesperson said: "Following enquiries into the ongoing security alerts in Derry/Londonderry this morning, and the arrest of a 39 year old man, police can confirm that they are not investigating any link between these alerts and the murder of Lyra McKee in the city on Thursday night"
During Sunday's alert a section of the Strand Road close to the PSNI station was shut to traffic.
Police later confirmed alerts on Insicarn Road and Harty Court have ended.
Suspicious objects discovered in both areas have been examined by ammunition technical officers who declared them to be non-viable devices.
They have now been removed for further examination.
Two other alerts, on Strand Road and in Moss Park, remain ongoing.
