Bryon Bay woman Sara Connor has been charged with murder in relation to the death of a Bali policeman on Kuta Beach.
She is also facing charges of assault causing death and group assault.
The 45-year-old mother of two was questioned throughout Saturday afternoon, before her lawyer emerged to reveal the charges.
Bali Police Chief Sugeng Priyanto earlier told the ABC her British boyfriend, David Taylor, had also been charged with the same crimes.
Connor’s lawyer Erwin Siregar, who also represented Australian Schapelle Corby, said she had signed a document enabling police to detain her for the next 20 days while investigations continued.
That time can be extended by police to up to 100 days.
“We will continue to meet Sara by next Monday — she is too tired, that’s why we stopped the investigation today, otherwise we would be here until midnight,” Mr Siregar said.
“She is tired and, of course, sad — that is normal.”
Mr Siregar said Connor had arrived in Bali on Tuesday and Taylor met her at the airport, where they bought beer before returning to the man’s homestay.
“Then they are going to the restaurant, she drank a beer, and then they are going to the beach with two beer bottles, one each,” he said.
Mr Siregar said the man and woman had been kissing on the beach after arriving at 11:00pm and leaving around 3:00am.
“No, no, no, no drugs involved,” he told media outside the Denpasar police station, where the pair is being held.
Pair had wounds examined in hospital
Earlier in the day the suspects were taken to the Bali Police hospital to be forensically examined.
“We performed forensic examinations on the wounds suffered by the people of interest,” Denpasar Police Chief Hadi Purnomo said.
He said that was to determine “whether the wounds are new or old, including the forensic examination of the nails”.
The Bali policeman, Wayan Sudarsa, was found dead on Kuta Beach in the early hours of Wednesday morning with 42 wounds to his body, including to his head and neck.
Police say they may have been caused by a broken beer bottle.
A cleansing ceremony was held at the sight of his death on Kuta beach this morning, the policeman will be cremated by his family tomorrow.
The murder charge carries a maximum of 15 years in jail.
