An investigation is under way into an arson attack at a house in Drogheda that was searched as part of the Keane Mulready-Woods murder investigation.

The 17-year-old was kidnapped and killed in January and his partial remains were found at separate locations in Dublin.

Fire crews were called to an address in the Rathmullen Park area of Drogheda at around 2am after an oil tank in the garden was set alight.

No injuries are reported.

It is understood the fire did not spread due to a low level of oil in the tank.
