A 22-year-old man is to appear in court in Derry today in connection to a window display at premises on Chamberlain Street in the city.
Police said he had been arrested on suspicion of committing an offence under Section 13 Terrorism Act 2000.
He has been charged to appear at the courthouse in Bishop Street today.
The painting, which appeared last month on a window at Junior McDaid House in Derry, shows a snowman figure dressed in an beret, adorned with an Easter Lily and snood-style face covering.
The cartoon character is beside what appears to be a switch button attached to a length of wire running to a Christmas tree, which has been lit up.
A Santa figure is also seen wearing an Easter Lily, a pair of gloves and holding a radio.
The image includes the words "they haven't gone away ye know", a quote from former Sinn Féin president Gerry Adams, made in reference to the Provisional IRA in 1995.
