Prosecutors have directed no prosecution of Sinn Féin President Gerry Adams over claims he withheld information about his brother's sex abuse from the police.

Gerry Adams has been accused of waiting almost a decade to tell detectives what he knew about his brother Liam.

Liam Adams was convicted this week of abusing his daughter Áine from when was she aged four until she was nine.

The PSNI confirmed a decision was taken in 2010 by the Public Prosecution Service not to launch a case.

Assistant Chief Constable Drew Harris said: "This matter has been examined to see if we should open an investigation into the case and the advice that we received was not to open an investigation.

"We will re-examine the transcripts (of the recent court case) but all the facts in our knowledge in 2010 have not been moved on materially since the recent trial."

Liam Adams, 58, from Bernagh Drive, Belfast, was found guilty of ten offences, including rape and gross indecency, against his daughter.

The abuse was committed over a six-year period between 1977 and 1983.
