Gardaí in Drogheda say the area is being 'well-policed' in case of retaliation attacks after the murder of Keane Mulready-Woods.
The remains of the 17-year-old were found in a sports bag in Coolock in Dublin on Monday night.
Detectives are also examining whether remains discovered in a burnt-out car in Ballybough yesterday belong to the teenager.
No arrests have been made in connection with the murder, while a house is currently being examined in Drogheda in connection with the investigation.
Gardaí yesterday said the "brutal and savage" murder is related to the ongoing feud in Drogheda.
According to Chief Superintendent Christy Mangan, the "horrific murder of a child" is part of an ongoing unacceptable level of violence in the Drogheda area.
He said: "Unfortunately the persons involved are intent on inflicting maximum damage on each other at this point.
"We have the area well-policed in relation to ongoing criminal activity."
He added that potential retaliation is "one line that we certainly will be managing".
He also reassured the public that they are carrying out a "very, very extensive" investigation into the murder and that they've been given additional resources as part of their work.
Meanwhile, some people in Drogheda say they're nervous following the murder of Keane Mulready-Woods.
One man told Newstalk's Henry McKean: "Leave the kids alone - that's basically it. Let them live."
Another woman suggested: "You would be nervous coming down the town, [especially] older people. I was listening to the helicopter going around last night."
