A series of security alerts which resulted in the arrest of a man, and the evacuation of a number of homes in Derry have now ended.
Suspicious objects discovered in on Insicarn Road and in Harty Court have been examined by ATO who declared them to be non-viable devices. They have now been removed for further examination.
Police have also confirmed that they are not investigating any link between these alerts and the murder of Lyra McKee in the city on Thursday night.
A 39 year old man who was arrested in the city this morning is being questioned by PSNI officers in Belfast.
