BELFAST, Northern Ireland (AP) — Northern Ireland police were granted an extra 48 hours Friday to interrogate Sinn Fein leader Gerry Adams about the 1972 IRA killing of a Belfast widow, infuriating his Irish nationalist party and raising questions about the stability of the province’s Catholic-Protestant government.

The Police Service of Northern Ireland confirmed in a statement its detectives received permission at a closed-door hearing with a judge to detain Adams for up to two more days.
