Police investigating the murder of a sports official in Northern Ireland in 1997 have made another arrest.
Sean Brown's body was found in a burned out car
Sean Brown, 61, was shot dead as he left his local Gaelic Athletic Association (GAA) club in Bellaghy, County Londonderry.
A 39-year-old woman, originally from Northern Ireland, was arrested on Thursday morning at a house in Waltham Crescent in Nuneaton, Warwickshire.
A man arrested at the same address on Wednesday is still being questioned.
The woman is currently in custody in Nuneaton awaiting questioning by officers from Northern Ireland.
The 44-year-old man was also to be questioned by PSNI officers.
A police spokesman said the man was also originally from Northern Ireland but was living in the Warwickshire area.
The murder of Mr Brown was featured in a reconstruction by the BBC's Crimewatch programme in June.
A GAA match was recreated for the programme, and poet Seamus Heaney and Church of Ireland primate Archbishop Robin Eames were interviewed.
Last year Sean Brown's family reached agreement with PSNI Chief Constable Hugh Orde on how a new investigation should proceed.
It followed a critical report from the police ombudsman on the original Royal Ulster Constabulary (RUC) investigation into Mr Brown's death.
In January 2004, Police Ombudsman Nuala O'Loan said she had upheld two complaints from Mr Brown's family about the RUC inquiry into his murder.
A new team of investigators, including officers from outside forces, started a new inquiry.
