Gardai are hoping to question a suspect in the murder of Ashling Murphy as early as today.
A person of interest in the killing of the 23 year old school teacher is understood to still be receiving hospital treatment for a number of injuries and will need to be assessed before he can be questioned.
Ashling was attacked while going for a run along the banks of the Grand Canal in Tullamore last Wednesday.
Her death has led to calls for 'zero tolerance' of violence against women.
University College Cork runs a Bystander Intervention programme which educates students and staff about how best to intervene when they witness inappropriate behaviour or comments, Professor Louise Crowley says failing to address sexist attitudes, communicates that the behaviour is acceptable.
"Making an intervention can be difficult for people, intervention inhibition is entirely understandable.
"We work with the participants to understand their fears, but also to realise that witnessing something and not speaking out about it means that you are part of the problem in that you are somewhat implicitly suggesting that that behaviour is ok.
"We do try to cultivate that sense of personal responsibility and that desire to contribute to change."
