A woman has appeared in court accused of threatening to kill her sister.
Siobhan Whelan, of Campion Court, is further charged with criminal damage, possessing an iron bar and a knife and making a threat to damage property.
The charges relate to an alleged incident in the city on June 4.
Derry Magistrates Court heard allegations that the 23-year-old let herself into her sister’s flat and became abusive.
She was drunk at the time and when she was asked to leave, she allegedly threw a cup at her sister and pushed her.
The court heard further allegations that Whelan had threatened to kill her sister before leaving for a short time.
The 23-year-old allegedly returned to the flat and used an iron bar to smash a pane of glass in the door.
She also allegedly threatened to burn the flat down.
An investigating officer told the court Whelan had left the property when police arrived, however she returned and asked to use the bathroom.
It is alleged that after she was arrested police found a large kitchen knife in the bathroom wrapped in a pair of pyjamas.
During police interview, Whelan denied that the knife was hers and claimed she couldn’t remember what happened because of the amount of alcohol she had consumed.
Opposing bail, the officer said police fear the 23-year-old may interfere with witnesses or commit further offences.
She added that Whelan has issues with alcohol and ‘becomes angry when she drinks a lot’.
Defence solicitor Maeliosa Barr applied for his client to be released on bail with conditions.
He added that Whelan does not have any previous convictions for violence and there has been no history of domestic incidents between the sisters.
Deputy District Judge Anne Marshall released the 23-year-old on her own bail of £250, banned her from having contact with her sister and from going into the estate where her sister lives.
Whelan is also banned from being drunk in a public place.
She will appear in court again on July 4.
