Gardaí investigating the deaths of two children in a car fire in Co Westmeath expect to question "a person of interest" before the end of this week.
The suspect identified by investigators is the only person Gardai want to speak to at this stage.
Meanwhile, Gardai confirmed yesterday that a criminal investigation was underway into the deaths of two-year-old Mikey Dennany and his five-year-old sister Thelma who died in the car fire last Friday just outside Multyfarnham.
Their bodies were released to their family yesterday and funeral details are expected to be announced later today.
Last night gardaí issued an appeal to anyone with information to come forward.
They are particularly interested in speaking to road users or others who were in the area of Lacken, Multyfarnham, between 2pm and 4pm last Friday.
