A group of TDs from Louth has called on the Government to increase the number of gardaí in Drogheda following the outbreak of a feud between two criminal gangs in the town over the past week.

Fine Gael TD Fergus O'Dowd said families are "fraught and distressed" by what is happening in their community.

He said there is a deficit in garda numbers in Drogheda as there are 107 officers in Drogheda and 159 in Dundalk, even though the two towns are of a similar size.

Fianna Fáil TD Declan Breathnach said he flagged the "thuggery and crime" in Drogheda to Minister for Justice Charlie Flanagan in June.

Sinn Féin TD Gerry Adams said incidents of drug-related crime in Dundalk and Drogheda have risen to "an intolerable level" and An Garda Siochana deserves the "fullest support" of the Dáil.

He renewed calls for a specialist drugs unit for Louth "which was previously promised".

Responding to the TDs in the Dáil this afternoon, Minister Charlie Flanagan said he understands the concerns being expressed by the people of Louth.

He said the garda commisioner is responsible for the distribution of resources and this is kept under continuous review to make sure the best use is made of the resources.

He added that An Garda Síochána has put in place a policing operation to mitigate any further escalation of violence in Drogheda.

Mr Flanagan said that in addition to cancelling all garda leave in the Louth division for the next two weeks, the operation will entail high visibility patrols with support from units such as the regional armed support unit.

He pledged that the gardaí will make every effort to arrest and prosecute offenders involved in the feud. 

Four men arrested in connection with an incident in the Moneymore Estate in Drogheda on Sunday were released without charge.

A file is being prepared for the Director of Public Prosecutions.

A fifth man remains in garda custody.

Investigations are being held into an assault, kidnapping and petrol bomb attacks in the town.
