Four Dublin councillors will table an emergency motion at today's city council meeting, calling on Justice Minister Helen McEntee to act on previously suggested changes to knife crime laws.
The move would double the sentence for knife crime to 10 years.
Former Fianna Fáil justice spokesman Jim O'Callaghan had proposed the change.
However, the Government has said there are no plans to amend the current legis- lation.
In the space of just over a week, Dublin's north inner city has witnessed a spate of knife crimes.
A 14-year-old boy has been charged in connection with a knife attack that led to an office cleaner needing life-saving surgery after she was stabbed in the neck on January 20.
Last Tuesday, a teenager was stabbed on East Wall Road and died from his injuries.
Two days later, a man was stabbed in Seville Place.
The four councillors - Nial Ring, Christy Burke, Anthony Flynn and Cieran Perry - will call on the justice minister to immediately reintroduce Mr O'Callaghan's private mem- ber's bill.
The councillors will also call on the minister to immediately set up a task force to address, research and analyse the causes of the increase in knife crime.
Last October, around the time of the sentencing of a youth for the killing of Dublin teenager Azzam Raguragui, a Justice Department spokes- man said the Government is "very aware of the concerns which many members of the public hold with regard to the issue of knife crime".
Mr Ring said the impact of the recent knife attacks cannot be underestimated.
"People are literally living in fear and looking to the authorities for action," he said.
Mr Perry said legislation is "only one part of the jigsaw, but ultimately we need buy-in from the affected comm- unities".
