Veteran republican Marion Price is one of three people to have been charged in relation to terrorist offences over the weekend.
The PSNI said this morning that a 57-year-old woman, understood to be Ms Price, will appear in Londonderry Magistrates Court tomorrow, Monday 15 May.
Police said she was being charged in relation to her involvement in an Easter Monday Parade on 25 April in Londonderry, specifically, encouraging support for a proscribed organisation.
A spokesman said she had been arrested by the PSNI Serious Crime Branch in west Belfast on Friday, under section 12.3 of the Terrorism Act 2000.
Price, 57, and her sister Dolours were among those convicted of a 1973 bombing near the Old Bailey in which one person was killed and almost 200 others injured. She split with Sinn Fein around the time of the Good Friday Agreement in 1998 and is now a spokeswoman for the 32 County Sovereignty Movement, considered to be the Real IRA’s political wing.
A man and another woman have also been charged with encouraging acts of terrorism. They were arrested on Saturday morning by detectives from the Serious Crime Branch who were investigating alleged dissident republican.
The 25-year-old man from Lurgan, and the 26-year-old woman from Armagh, will appear before Lisburn Magistrates Court on Monday. The PSNI said each had been charged with one count of encouraging acts of terrorism under section one of the Terrorism Act.
