Meanwhile, a man being questioned by Gardai investigating the murder of the Tullamore school teacher was released without charge last night.
The 23 year was killed on Wednesday afternoon as she jogged along the banks of the Grand Canal in Tullamore, Co. Offaly.
In a statement Gardai confirmed that the man who'd been arrested and detained for questioning had been released without charge.
They say he's been eliminated from their enquiries and is no longer a suspect.
Gardai have renewed their appeal for any information on a Falcon Storm mountain bike with straight handlebars and distinctive yellow/ green front forks.
The force also appealed for any person with any information on the fatal assault, who may not already have spoken to investigators, to come forward with that information.
