A man arrested in connection with arson attacks on a vacant detached house on the Celbridge Road in Leixlip has been released without charge.
The property had been at the centre of online rumours and local protests.

The man, in his 30s, was arrested yesterday morning and has since been released pending a file being prepared for the Director of Public Prosecutions.
The investigation relates to two separate fires on the Celbridge Road - one in the early hours of January 30th and another on February 7th last year.
The February blaze broke out at the privately-owned seven-bedroom property shortly after 1.30am and caused substantial damage to the empty building, known locally as Honeywood.
It is located near the Forest Park estate, adjacent to Barnhall Shopping Centre.
Fire crews brought the fire under control and no one was inside at the time.
The investigation is continuing.
