he thought suicide would "ruin his children's lives".
Nishanthini Nithiyakumar, aged 41, of Ilford, has been sentenced to a hospital order for killing his two children during the first lockdown.
Central Criminal Court heard that police were called to an address in Newbury Park at around 5:30 pm on April 26, 2020, to reports of a man and two children having been injured.
Pavinya, aged 19 months, was pronounced dead at the scene while her three-year-old brother, Nigish, was rushed to hospital where he later died.
The children’s mother Nisa was in the shower at the time of the killings and informed the police.
Neighbours recalled how his wife ran into the street screaming from the couple’s flat following the attack.
Nithiyakumar was found with self-inflicted knife wounds and was also taken to hospital.
After he was discharged, Nithiyakumar was arrested on April 29 and initially charged with murdering his two children.
It was reported that Nithiyakumar “exploded” during lockdown and attacked his children after finishing his shift.
The shop worker told police that he returned home from work in the CVS Superstore in Hainault after customers had “upset him” and he considered taking his own life.
Nithiyakumar accepted he had killed his son and daughter with a knife, saying he came to the decision because he thought suicide would “ruin his children’s lives”.
Evidence found there to be no such disagreements between customers and Nithiyakumar that day.
Medical experts for both the prosecution and the defence agreed that Nithiyakumar was suffering from an undiagnosed psychotic mental illness at the time.
On November 5, 2020, Nithiyakumar’s plea to diminished responsibility manslaughter was accepted.
On December 10, 2020, he was sentenced to a hospital order under section 37 of the Mental Health Act 1983 and s41 restriction order under the same Act.
Devi Kharran, Senior Crown Prosecutor for the CPS, said:
“This was a tragic case in which a loving and devoted mother had her two children cruelly taken away from her.”
“The man responsible for killing them was trusted to keep them safe and his wife had no reason to believe he was preparing to commit such awful crimes.
“She was in the shower at the time of this incident.
“She was completely unaware that he was at the time suffering from a delusional disorder which led him to take the terrible decision to kill his children, in a misguided attempt to protect them, before attempting to kill himself.
“The CPS accepted the views of three medical experts that he was clearly driven to this by a serious medical disorder.
“Throughout this case, the prosecution and the police have supported the children’s mother through what have been very traumatic and difficult court proceedings. Our thoughts remain with her at this time.”
