A man carried out an arson attack on his neighbour’s home after pouring an accelerant over the front door, Lincoln Crown Court was told.
Sean Kay, who had fallen out with his neighbour Jason Lusby, used a lighter to start the fire sparking a flash flame.
Robert Sandford, prosecuting, said that the blaze burned itself out and the damage was discovered by Mr Lusby when he returned with his partner to their home at Breedon Drive, Lincoln.
Mr Lusby immediately suspected Kay, who lived in the adjoining first floor flat, and went to confront him.
Mr Sandford said: “The defendant emerged from his flat and said ‘I did it because I hate you. I wanted to burn you out’.
Police were called to the scene and when officers arrived Kay again made a confession to them.
Later when he was interviewed Kay said he had been subjected to name-calling by Mr Lusby.
Mr Sandford said “The defendant believed he had been persecuted by the complainant.”
The court was told that Kay suffered a brain injury in 2011 which has affected his behaviour.
Kay, 54, formerly of Breedon Drive, Lincoln, admitted a charge of arson arising from the incident on December 27, 2015.
He was ordered to be detained at St Mary’s Hospital, Warrington, under the 1983 Mental Health Act.
Judge Simon Hirst, passing sentence, told Kay: “I am satisfied that you are suffering from a mental disorder.”
Michael Cranmer-Brown, in mitigation, urged that a hospital order was the best way of dealing with Kay.
