A man attacked his ex-partner with a knife in a city centre park, leaving her with a slash wound from her forehead to her cheek, it is alleged.
Eddie Johnson (39) is accused of inflicting a "nasty" injury on the woman, who needed seven stitches to her face.
He appeared in Dublin District Court on assault and weapons charges after he was arrested in connection with the incident yesterday.
Judge Grainne Malone remanded him in custody for a week after no bail application was made on his behalf.
Mr Johnson, of no fixed address, is charged with assault causing harm to a woman at Wolfe Tone Park, Jervis Street, Dublin 1 on April 28.
He is also accused of unlawful possession of a knife in the incident.
Garda PJ Gallagher told the court he arrested the accused yesterday and brought him to Store Street Garda Station, where he was charged at 12.39am yesterday morning. Gda Gallagher said he would be objecting to bail.
Judge Malone asked him what was alleged.
Gda Gallagher said it was alleged the accused attacked his ex-partner at Wolfe Tone Park at 3pm yesterday, using a knife and inflicting a wound to her face.
The alleged victim sustained a "nasty injury", from her forehead to her cheek and required seven stitches to her face.
Defence solicitor Ruth Walsh said she was not making a bail application at this time and there was consent to the accused being remanded in custody.
Judge Malone said jurisdiction would have to be considered in the case, to determine whether it can be dealt with at district court level or if it will be sent forward for trial to Dublin Circuit Criminal Court.
She asked the garda if he wished her to consider jurisdiction but he said the directions of the DPP were awaited and the judge instead deferred this.
She remanded the accused in custody, to appear in Cloverhill District Court on May 6, by video link.
Mr Johnson, dressed in a striped jumper and wearing a face mask throughout the brief proceedings, was not required to address the court.
The charges against him are under the Non Fatal Offences Against the Person and Firearms and Offensive Weapons Acts.
Separately, he also is charged with theft and public order incidents in a city centre convenience store.
Mr Johnson is charged with public intoxication, threatening, abusive and insulting behaviour and stealing food items worth €5 at Londis, Westmoreland Street, in April 4 last.
He has not yet indicated how he intends to plead to any of the charges.
