The man suffered severe wounds to his face when a bomb went off as he was attempting, gardaí suspect, to plant it under a car.
The blast occurred on a narrow road in a densely populated row of terraced cottages in Dublin’ south inner city at around 11pm on Sunday.
No one else was injured in the bomb attack, which destroyed an SUV parked on the road.
“His entire face was covered in what I thought was blood, but now know were severe burns,” said one eye-witness. “He was running down the street with his hands up to his face screaming ‘please help me, please help me’.”
The eye-witness said the injured man was around 5ft11 in height, no older than 30 and wearing a green/blue sporty-type jumper.
He said the man ran straight into a car as he fled. He then ran onto New Street/Clanbrassil Street area.
Gardaí yesterday appealed to a taxi driver who they believe picked up the man on the street and drove in the direction of St Patrick’s Cathedral.
A garda spokesman said the man had suffered “significant injuries” and required hospital attention.
