Aamina Khalid, defending, said Scott had a “psychotic episode” and suffered a relapse of bipolar disorder when the incident occurred, and was “not able to understand what his actions were” as a result.
Scott was approached by armed officers who arrested him at the scene immediately after the incident, while the vehicle he was driving was subsequently destroyed, Westminster Magistrates Court heard on Thursday.
Johnny Scott, 26, drove his VW Polo into the south centre gate of the royal residence on March 9 last year, causing £24,493 in damage.
District judge Neeta Minhas told Scott: “You have caused a very high level of damage to a structure that is of huge cultural importance in the United Kingdom.
His family had called local mental health services “multiple times” before the incident and had even reached out to their local MP, she said.
