Detectives investigating the disappearance of a woman more than 10 years ago have today arrested a person who was just 11 at the time.
Sandra Collins vanished in her home village of Killala in Co Mayo on December 4, 2000.
A 21-year-old woman was arrested at 11am today and is being questioned at Ballina garda station under Section 30 Offences against the State Act 1939.
It is understood her detention could be in relation to withholding evidence in recent years.
Ms Collins was 29 when she was last seen. She had left her aunt’s house, where she lived and who she cared for, to go to the local shop and bought some groceries.
She was last seen at about 11.15pm, more than three hours later, at the local takeaway, The Country Kitchen.
Investigating gardai marked the 10th anniversary of her disappearance with a fresh appeal in identifying a white van in Killala at the time.
Ms Collins’ heartbroken sister Bridie and brother Patrick, who believe something bad happened to their sister either intentionally or by accident, have appealed for information to help them find the body to let them bury their sister.
The missing woman is described as 5ft in height with a small slim build, and short brown hair with red highlights
When last seen, she was wearing black trousers, a maroon polo neck jumper, a beige sleeveless jacket with a hood and black boots.
Four days later, on December 8, her fleece was found on the pier in Killala with a half-pound of sausages Ms Collins had bought in the shop still in the pocket.
