A man in his 30s has been arrested by Gardaí investigating the murder of Ashling Murphy.
He was arrested in a Dublin hospital earlier today, after being treated for self-inflicted stab wounds and other injuries.
The man has been taken to Tullamore Garda Station, where he can be held for 24 hours without charge.
It comes just hours after the 23-year-old schoolteacher was laid to rest in her native Offaly.
At her funeral service in Mountbolus this morning she was remembered as a kind, talented, loved and admired young woman.
Her First Class pupils from Durrow National School formed a guard of honour outside the church, and each held a red rose and a photo of their teacher as the cortege arrived.
Her cousin, Ciara Leonard, paid tribute to her.
“Ashling epitomised the beauty of life, and shared her passion, gifts and talents with others so generously,” she said.
“We pray for her friends, colleagues and students – may Ashling's legacy live in the hearts of all she touched.”
Ashling was attacked and killed while out jogging along the Grand Canal at Cappincur near Tullamore last Wednesday afternoon.
A man who was arrested shortly afterwards was later released with Gardaí announcing that he was no longer a suspect.
In recent days it emerged that investigators were focusing on a new suspect and were preparing to make an arrest.
Last night, they appealed for information on a man in a black tracksuit who was in the Tullamore area after the attack.
The killing has sent shockwaves through the country, with vigils held all over Ireland and beyond in the days since.
