Gardai have renewed their appeal for information into the murder of Ashling Murphy as "significant progress" continues to be made in the investigation.
The 23-year-old teacher was killed while out jogging at around 4pm along the canal bank in Tullamore, Co Offaly on Wednesday.
Gardai are currently examining the scene around a bottle bank in the town as part of the probe as they wait to question a suspect who is being treated at a Dublin hospital.
In their latest update, officers asked for people with any information pertinent to the investigation to come forward.
They also released further details about a man seen walking in Tullamore around the time of Ashling's murder.
Members of the force are asking the public if they recall seeing a man dressed in black tracksuit top and bottoms with a large white stripe or white writing on the side and black runners on Wednesday afternoon.
They added that the investigation is progressing but would not confirm any specific details "for operational reasons".
