London - A 17-year-old boy was scheduled to appear in court Tuesday on a murder charge in the slaying of a police officer earlier this month in County Armagh, a Police Service of Northern Ireland spokeswoman said.

The youth was charged late Monday in the killing of Constable Stephen Carroll. He faces additional charges of membership in the banned Continuity IRA, possession of a firearm with intent and collecting information likely to be of use to terrorists.

The officer suffered a fatal gunshot while responding a call about a brick thrown through a window.

Four other suspects remain jailed for questioning in the police officer's slaying. Earlier Monday, two men, aged 27 and 31, were released without charge in the case.

Four suspects are jailed in the killings of two British soldiers killed in North Ireland in a shooting two days before the Armagh attack. (dpa)
