A 44-year-old man is in a critical condition in hospital following a serious assault in Dublin.
The incident, in which the man was attacked by another man, happened on Prices Lane at around 10.25pm on Friday 26 April.
The injured man sustained life-threatening injuries and is being treated in St James's Hospital.
Following the assault, gardaí said the suspect made his way onto Aston Quay near its junction with Bedford Row, where he removed items of his clothing and appears to have laid down on the street.
Gardaí said his behaviour attracted public attention and they believe the man may have been recorded on mobile phones.
They are appealing to anyone who has mobile phone footage and to drivers who may have dash cam footage to contact them.
