The main suspect in the murder of Toyah Cordingley, who was found dead on a beach in 2018, was arrested in India on Friday.
According to Katarina Carroll, the police commissioner of Queensland, Singh had been hiding in Punjab. He is due to appear in court later in the day.
It is believed that he will be extradited to Australia to face trial.
According to Carroll, the police had been informed about Singh’s whereabouts before he was arrested.
She was pleased that the arrest of the main suspect was able to bring closure to the family of Cordingley.
It had been a case of waiting for the day that would come. I am very confident that the courts will find the evidence against Singh sufficient.
Singh, who used to be a nurse in the town of Innisfail, fled Australia two days after the body of 24-year-old Cordingley was found in the dunes of Wangetti Beach at the far north Queensland city of Cairns.
The Queensland Police Department had offered a $1 million reward to anyone who can provide information that leads to the arrest of Singh.
At the time of the announcement of the reward, Police Commissioner Katarina Carroll said she was not sure if the information provided by the public helped in the capture of the suspect.
Mark Ryan, the state police minister, said the investigation had involved hundreds of officers.
Detectives from the Queensland Police Department traveled to India earlier this month to assist the authorities in their search for Singh.
The family of Cordingley, who has been fighting for justice, is yet to comment on the arrest of the main suspect.
