The graffiti has since been removed.
Free Derry Corner, an iconic Republican mural, was vandalised on Thursday night with graffiti showing support for Soldier F.
The gable wall, which usually reads 'You are now entering Free Derry', was tagged with red graffiti which said the words 'Soldier F' beneath the logo of the British military's Parachute Regiment.
Soldier F is the name given to the British soldier who is facing prosecution over Bloody Sunday, which took place on the streets surrounding the Free Derry Corner.
It was announced in March of this year that just one member of the 1st Battalion of the Parachute Regiment would face charges over the events of Bloody Sunday.
He is expected to be formally charged with two counts of murder in relation to James Wray and William McKinney, as well as four counts of attempted murder.
13 civilians were killed on Bloody Sunday in 1972, with John Johnston dying later due to injuries he received on the day.
