Mr Justice Dove said a clinical psychologist had diagnosed Mr Hagos as having depression and PTSD as a direct result of the attack.

In a victim impact statement read in court by the prosecution, he said he continued to suffer “excruciating pain” in his hand and struggled to sleep.

“I had been living and pursuing a happy life before the incident,” he said. “This is now a distant memory.

“I feel lonely and don’t feel safe on the street. My life has been turned upside down.”

Bethan David, head of the Crown Prosecution Service’s counter terrorism division, said: “This attack was carried out to intimidate a section of the public – namely asylum seekers and those providing accommodation to asylum seekers.

“Callum Parslow’s neo-Nazi views motivated him to viciously attack a man based solely on the colour of his skin and the place he was from, and he sought to spread fear amongst a community.

“This was an act of terrorism.”
