Police in Northern Ireland investigating the disappearance of two young boys more than 50 years ago have renewed their appeal for information.
Eleven-year-old David Leckey and 14-year-old Jonathan Aven went missing in east Belfast in September 1969.
David was last seen at his home at Memel Street. Jonathan disappeared from his home at Sydenham Drive.
Both families said neither had given any indication of an intention to leave.
David's family said they had "no indication that he was unhappy or in trouble of any kind and didn't think he would ever have left home".
Jonathan was described by his family as a "happy little boy" who attended a local secondary school where he was getting on well.
The case is being looked at by the PSNI's legacy investigation branch.
Detective Inspector Armstrong said both families had suffered in the 56 years since the two boys were missing.
"This remains an open missing persons case with the circumstances around their disappearances still unexplained.
"The pain and suffering of not knowing throughout the years must be unimaginable," he said.
The officer said the investigative team was aware of reports that the boys might have taken a train to Bangor prior to their disappearance and were keen to speak to anyone who had encountered them in any circumstances or location in the intervening years.
"If anyone has any information in relation to the disappearance of David and Jonathan, we ask them to contact the legacy investigation branch where all information will be assessed and considered by investigators."
