The wife of a man who was severely injured after a scrambler bike landed on his head has hit out at the justice system after gardaí told her the teenage rider will not have to appear before a court.

Anzhela Kotsinian (44) has criticised gardaí, the 16-year-old rider and his parents for a "devastating" outcome to the case.

Ms Kotsinian, who is from Armenia, was sunbathing with her husband Ilabek Avetian (39) when he suffered a devastating brain injury after a scrambler bike ran over them in Darndale Park, north Dublin, last June 9.

The former teacher had moved to Dublin shortly before her husband was injured.

"My husband is lying in hospital clinging to life for the past 10 months," Ms Kotsinian said. "For those months I waited on justice and I waited on that boy's mother to say one word: 'Sorry'.

"Instead, I am told by a garda that our case is over, that the justice system decided the 16-year-old would not go into juvenile detention.

"They decided he didn't have any fault in this case and there would be no prison, nothing.

"This boy has broken my family.

"How can a boy run over my husband and I in the park when we sunbathe and nothing happens to him? Where is the justice? I am so angry."

Mr Avetian had been working as a plasterer and they planned to start their own business and restart IVF to have a baby when he was injured.

He lost his left eye and sustained multiple fractures to his forehead, nasal bones and jaw in the incident. He also suffered a severe brain injury and haemorrhage.

A Garda spokesman said: "A file was forwarded to the DPP for direction. This matter is to be dealt with by way of the Juvenile Diversion Programme (JDP)."

The scheme may involve a youth agreeing to engage in certain activities or report to a liaison officer. Ms Kotsinian said she had not been consulted on the process.
