Accused claims he was stabbed in Dublin on day Ashling Murphy was killed

The witness said Jozef Puska (pictured) called to his home at around 9pm on the night after Ashling Murphy had been found stabbed to death by the Grand Canal in Tullamore.
A witness has said that the man accused of Ashling Murphy's murder was covered in scratches on the night after her death and had told the witness that he had been fighting, the Central Criminal Court has heard.
The trial also heard on Tuesday that Ashling's final moments were recorded on a Fitbit watch which showed "erratic" or "violent" movements before her heart rate began to decrease and stop at the point along the Grand Canal in Tullamore where she died. She had been exercising on the canal towpath from 2.41pm until 3.21pm when the GPS showed that her location did not change, the court heard.
