Gardai are probing whether the shooting of a teenager in west Dublin could be a revenge attack following a horrific stabbing.
The two incidents are believed to be part of a local dispute between "up-and-coming gangs" in the west Dublin area.
So far, there have been a number of shootings and assaults reported to gardai, with most of those involved either teenagers or young adults.
The 19-year-old was shot in the leg on Le Fanu Drive, Ballyfermot, shortly after 10pm on Thursday night.
The victim was rushed to St James' Hospital where he was treated for non-life threatening injuries.
Sources have revealed that the shootings may be linked to the vicious stabbing of another teenager the previous week.
A 17-year-old was approached shortly before 6am on March 18, outside an address in Croftwood Gardens in Ballyfermot.
He was stabbed a number of times and suffered serious injuries to his chest.
He was discovered in the front garden of a house and emergency services were called.
He was rushed to St James' hospital, where his condition was described as stable.
Gardai are now considering a link between the stabbing incident and last week's shooting.
However, despite suffering serious injuries the youth has so far refused to assist detectives with their inquiries.
Gardai have also increased the number of resources in the west Dublin area in the last number of months in an attempt to keep a lid on tensions between the two groups.
No arrests have been made.
