At least three families have been forced to flee their homes in recent days as a result of increased hostilities over the past week.
Shots were fired at three houses early yesterday, bringing to 11 the number gun attacks since Thursday of last week.
Feud-related shootings have occurred on five of the last seven nights.
A 16-year-old boy who was seriously wounded in one shooting was said to be comfortable at the Mid-Western Regional Hospital.
The boy — an innocent bystander — was hit when a gunman fired a semi-automatic weapon in Southill last Thursday.
The intended victim was in a car near to where the boy was standing.
It is believed that relatives of one feuding family have travelled from their homes in Birmingham in recent days in response to a plea for reinforcements from relatives in Moyross.
The occupants of three houses in Hyde Villas and Clarina Avenue left their homes yesterday to take refuge elsewhere in the city after recent attacks.
An attempt was made to burn down one house on Monday night.
Chief Superintendent Willie Keane, head of the Limerick garda division, has deployed additional armed patrols to deal with the escalation in the ongoing feud.
He said: “We have increased our patrols. We already have 24-hour armed patrols, but these have now been increased.”
People associated with the Keane-Collopy and Ryan McCarthy-Dundon factions have been targeted in this latest escalation in the feud.
The home of the leader of the McCarthy-Dundon gang, ‘Mr Big’, who was last month sentenced to 11 years at London’s Southwark Crown Court, was shot at in one incident. His wife and young family live in the Ballinacurra Weston area.
Mr Big, aged 27, was jailed for his involvement in a gun sales depot where a powerful Mach 11 machine pistol was offered for sale.
It is believed a gang based in Moyross have brought reinforcements from England.
During the past week the homes of two women widowed by the feud were also shot at.
The home of Mr Big’s elderly grandmother was also hit by gunfire. Some months ago an explosive device was thrown at the woman’s home.
