Another woman was arrested on suspicion of attempted murder over the incident.
Police are appealing for witnesses after the victim, who is in her 20s, was struck in the face in Enfield Parade in north Belfast.
She was taken to hospital for treatment to her injuries, which are not thought to be life-threatening.
The incident was reported to police at around 10.45pm on Saturday.
A 35-year-old woman was arrested and taken to Musgrave police station for questioning.
Detective Sergeant McPhillips said: “We would appeal to anyone who witnessed this incident or has information about it to contact police on the non-emergency number.
“Alternatively, if someone would prefer to provide information without giving their details, they can contact the independent charity Crimestoppers.”
It’s understood the incident was over a dispute between neighbours that “got out of hand”.
Local PUP councillor Julie-Anne Corr-Johnston described the attack as “horrifying”.
“I am very shocked to hear about the severity of the incident, which is now being treated as attempted murder,” she said.
“The circumstances surrounding the incident are unknown but we do understand that it was a neighbour dispute and police are appealing for information to try and piece together what happened.
“I understand the woman did not suffer life-threatening injuries.
“However, this was a nasty attack that could have ended very badly, as it got out of hand.
“My thoughts are with her and I hope she has a speedy recovery.
“I would urge anyone with information to come forward and if they don’t want to share their personal details they can contact Crimestoppers, or they can contact me.
“This incident has sent shockwaves through the local community.
“Just last week we had a young man, Paul McCready, who died after he was attacked and he leaves behind two young children and a fiancée, and we certainly don’t want a repeat of that.
“We don’t want any more violence on our streets.
“This happened in a busy area with people in local bars and takeaways, so someone may have spotted something.”
