Caroline Graham murder: Woman arrested in Portadown released
A 76-year-old woman questioned by detectives investigating the murder of a teenager 25 years ago has been released.
Caroline Graham was 19 and was living with her boyfriend at Hanover Street, in Portadown, County Armagh, when she disappeared in April 1989.
Originally from Newry, it is believed she had lived in Portadown for about two years before her disappearance.
The pensioner was arrested in Portadown on Tuesday morning.
She was released unconditionally several hours later.
Caroline's body has never been found.
Detectives investigating her disappearance launched a murder inquiry in August 2012 after they said they had a number of new lines of inquiry.
Areas of waste ground and parts of premises, including a well, were searched.
Police said they used sniffer dogs, probes, scanners, structural engineers and an underwater search team but "nothing of significance was found".
