The face of man who punched woman on Dublin bus
Gardai have appealed for help to find this vicious thug who attacked and punched an innocent woman on a Dublin bus.
The victim, who was travelling home, was struck a number of times by the unidentified assailant.
A major investigation is now underway to identify and question the person who assaulted her.
CCTV from the city bus may yet prove critical to investigating officers.
The injured woman spent a night in hospital following the assault which occurred on Wednesday night.
A friend of the woman suffered a bruised eye when he intervened to stop the thug.
Shocking scenes have emerged of the incident which happened on the top deck of the number 40 bus near Old Kilmainham Village at about 10.15pm.
A video, which has since emerged online, showed the young woman repeatedly punched in the face.
A source told the Herald that the woman had been on the bus with her flatmate and that she did not know who her assailant was.
"They were sitting on the bus when this guy just went psycho. He was an absolute scumbag.
"There was a guy at the back of the bus winding him up and egging him on," the source said.
In the video, the innocent woman was in the middle of the upper deck of the bus just before the attack began.
The man, who was wearing a blue t-shirt, suddenly got up and aggressively moved up the aisle towards her and started hitting her in the head and face.
The victim tried to defend herself and used her hands to cover her face before the attacker fled.
Dublin Bus yesterday told the Herald: "The driver stopped the bus and called the incident in to the central control team who alerted the emergency services. An ambulance arrived at the scene and took the woman to hospital."
It is unknown where the attacker fled to.
A garda spokesman told the Herald that they are investigating the incident.
There were 18 passengers on the bus at the time and gardai are appealing for witnesses to come forward and provide them with any information they may have.
The number 40 bus operates between Finglas Village and the Liffey Valley Shopping Centre.
