The PSNI has met with the family of a young man who went missing after escaping from police custody.
The father of David Colhoun from Lifford has said he fears his son has drowned.
The 22-year-old was arrested in Strabane on Saturday night for what the police describe as minor offences. He ran off while being transferred between police cars.
Searches of the River Mourne have been taking place.
PSNI chief Inspector Andy Lemon said the meeting was to reassure the family.
"We understand that one of the failings is we have not kept everybody informed as well as we possibly should," he said.
"Really, what the meeting was about was the fact that we were not telling the wider family.
"That is criticism I will accept, we should have been telling the wider family.
"The meeting was good in that we were able to discuss with the wider family what we have done and how we have done it."
Earlier this week, David's father, Joseph Colhoun, said it was a terrible time for the family.
"There's different rumours going about, but the last sighting of him was from a taxi man," he said.
"He was seen on the bridge heading towards Lifford in the early hours of Sunday morning.
"It is a living hell. I only buried my wife. She passed away on 7 January.
"It's just a bad dream.
"He's not alive. If he was and in anyone's house, everybody knows what's going on within a 100-mile radius and they would have sent him home.
"It's about finding him and giving him a proper burial."
