Constable Carroll was from Banbridge in County Down
A 17-year-old is due before magistrates charged with the murder of Constable Stephen Carroll in County Armagh.
Constable Carroll, 48, was shot dead as he answered a call for help in Craigavon on Monday 9 March.
The teenager is also accused of having a firearm with intent to endanger life and with membership of a proscribed organisation, the Continuity IRA.
He will face an additional charge of collecting information likely to be of use to terrorists.
The youth, who cannot be named, will appear at Lisburn Magistrates Court on Tuesday.
On Monday two men aged 27 and 31 - who were arrested last week in connection with Constable Carroll's murder - were released without charge.
Four other people are still being held over the murder.
The Continuity IRA said it shot Constable Carroll in the back of the head as he sat in an unmarked patrol car at Lismore Manor.
His murder came just two days after the killing of two soldiers at Massereene Army barracks in Antrim.
They were Sappers Mark Quinsey, 23, and Patrick Azminkar, 21.
Also on Monday, six people being held in connection with the murders of the three men launched a High Court challenge to the extension of their detention period.
