Gardai are appealing for the public's help in tracing the movements of the car in which the bodies of two young brothers were discovered in Co Mayo.
The remains of 5 year old Ruairi and 10 year old Eoghan Chada were found in the boot of a green Ford Focus car - which crashed outside Westport.
They were last seen leaving their home in Bagnalstown in Co Carlow - in the company of their 43 year old father Sanjeev - who was injured in the accident.
Gardai believe the childen died prior to the accident - which happened shortly after 3 o'clock this afternoon.
Superintendent David Taylor - from the Garda Press Office - is asking anyone who saw the green Ford Focus registration 06 CW 238 - to contact Gardai:
The boys were last seen in the company of their father Sanjeev Chada last night.
Earlier a Child Rescue Ireland (CRI) alert was issued in relation to the two boys. This was the first time the 'Amber Alert'-style system was used here.
They were reported missing at 1.30am on Monday. Mr. Chada left the family home at Ballinkill in Bagnalstown at 6.30pm last night in the company of his two children en-route to the Dome Bowling Centre in Carlow Town and never reestablished contact.
Mr. Chada was driving a green Ford Focus registered number 06-CW-238. These details were used as part of the alert that was issued, with the registration being posted on all NRA signs around the country.
