A 61-year-old woman arrested in connection with the murder of a man at a nursing home in Randalstown in Co Antrim has been released unconditionally.
The woman was arrested by detectives from the PSNI Serious Crime Branch earlier today.
Seamus McCollum, 56, died suddenly last September.
However, his death was not treated as murder until the results of a post mortem in April of this year.
Mr McCollum had cerebral palsy and had been a resident of the care home for nine years.
