A murder investigation is under way following the disappearance of an eight-year-old boy.
Kyran Durnin was reported missing to gardai in August, but had not been seen for some time before.
Gardaí began a missing persons inquiry but said in spite of extensive inquiries they have been unable to find Kyran or identify any information on his current whereabouts.
"Despite extensive enquiries carried out by Gardaí to date, An Garda Síochána have been unable to either locate Kyran, identify any information on his current whereabouts or any evidence that he is currently alive," a Garda spokesperson said.
"Following enquiries to date, investigating Gardaí now believe that Kyran is missing presumed dead. A murder investigation has been commenced".
The investigation is being led by a Senior Investigation Officer (SIO) based out of an incident room established at Drogheda Garda Station.
Gardaí are appealing to anyone who has any information in connection with the disappearance of Kyran to contact Drogheda Garda Station on 041 987 4200 , the Garda Confidential Line on 1800 666 111 or any Garda Station.
"Any information, no matter how insignificant it may seem, will be welcomed by the investigation team. This information will be treated in the strictest confidence," Gardaí said.
No arrests have been made as of yet, and the investigation is ongoing.
TUSLA, the Child and Family Agency, is working closely with and fully co-operating with this Garda investigation.
