Strike-marks made by nails were found in the kitchen of a house in Limerick, where a 53 year old man was allegedly nailed to the floor, the Special Criminal Court has heard.
The alleged victim, Dan Quilligan, has previously told the court that two or three men assaulted him before his left foot was nailed with a nail-gun to the kitchen floor.
Mark Heffernan (32), Swallow Drive, John Carew Park, Limerick, has pleaded not guilty to assaulting Mr Quilligan, causing him harm, at 6, Larch Court on September 14, 2015.
He has also denied falsely imprisoning Mr Quilligan at the same address on the same date.
It is the prosecution's case that three men were involved in a "joint enterprise" during which Mr Quilligan was hit in the face and his left foot was nailed with a nail-gun to the kitchen floor.
Today Detective Garda Alan Curry, of the ballistics section at the Garda Technical Bureau, told prosecuting counsel Tara Burns SC that he conducted a forensic examination of the house at Larch Court.
He found a number of "strike-marks" on the kitchen floor, he said.
The court heard that two of the strike-marks were consistent with having been "struck by a nail".
The trial continues in front of Mr Justice Tony Hunt, presiding, sitting with Judge John O'Hagan and Judge Ann Ryan.
