Gardai have still not spoken to an 18-year-old student who was the victim of a vicious assault 16 days ago.
Maynooth University student Kym Owens remains in the intensive care unit of Connolly Hospital in Blanchardstown and so far has been too ill to speak to investigating officers.
It is understood gardai "are hopeful" to be in a posi- tion to interview her later this week.
A chief suspect has not been identified, but gardai say they are making "good progress" in their investigation.
In an unusual appeal, a senior officer said yesterday that gardai would like to speak to some of more than 200 people who have already made statements in case anyone had "forgotten" to tell officers anything.
"They can come back to gardai in full confidence, they will not be in trouble or anything like that. Their information could be crucial," the source said.
The Herald previously revealed that gardai are extremely concerned that Kym may not remember anything about the attack.
She was viciously beaten in Maynooth on November 20 on her way to her college accommodation.
She had just got off a private bus and was set upon while walking to her digs at the Moyglare Abbey Estate.
The investigation has already been hampered by poor-quality CCTV because of fog.
