A man who is alleged to have put a pillow over his girlfriend's face before punching her up to 40 times had been refused bail.
Joe McDermott was remanded in custody at Londonderry Magistrates Court yesterday.
The 34-year-old, from Drumard Close in Derry, is alleged to have pulled his partner by the hair during a two-hour-long ordeal. He is also alleged to have attempted to strangle her.
He is further charged with stealing money from the complainant.
The woman made her allegations to police officers who were wearing body cameras, but she is refusing to make a formal statement.
She has said she will not take part in any police investigation into the incident, which is alleged to have occurred on Thursday.
An officer told District Judge Steven Keown that the complainant also told the police that her partner had threatened to murder her.
The officer said both the defendant and the complainant were suspected heroin users and that there was a domestic violence history between the couple.
The police witness said there were concerns for the safety of the complainant, and that two bail addresses put forward by the defendant were not acceptable.
Defence solicitor Don Mahoney said on his way to court he received a phone call from the complainant during which she said she was not going to cooperate in any way with the police.
Mr Mahoney said he quickly ended the conversation but shortly afterwards received several text messages from the complainant, which he forwarded to police.
In one of the text messages the complainant said she was planning to return to her family home in Raphoe, Co Donegal.
"She vigorously maintains she is not taking part in any investigation," he said.
Refusing bail, the judge said the allegations involved the defendant putting a pillow over the complainant's face before punching her between 30 and 40 times, pulling her hair and attempting to strangle her.
The defendant was remanded in custody until June 18.
