THE motorbike used by two gunmen in a failed hit on former bouncer Gerry O'Neill was caught speeding away the scene on CCTV.
Gardai are hoping to be able to compile a description of the gunmen who botched their attempt to kill the 33-year-old.
Doctors say it is an "absolute miracle" that O'Neill survived the attack on Tuesday night as a bullet missed major arteries by millimetres.
He was hit in the back of the head but the bullet exited through his mouth.
The getaway bike was found near Spencer Dock and is being examined by garda specialists as O'Neill continues to be treated in the Mater Hospital.
"He is extremely lucky to be alive," a source said, adding that O'Neill is expected to make a good recovery.
This was the second botched murder attempt on O'Neill who survived being shot at point-blank range last year.
The former bouncer was able to drive himself to Store Street Garda Station after being shot in the Sheriff Street area where he was visiting family members at about 9.15pm on Tuesday.
He managed to drive his silver Mercedes on to Amiens Street while being pursued by the gunmen who continued to fire shots on a busy Dublin street.
O'Neill turned into Store Street Garda Station at Busaras where a final shot was fired at his car as he veered on to the pavement.
He then ran into the garda station with blood pumping from his head as the motorcycle raced from the scene in the direction of the northside docks.
A Dublin Fire Brigade Ambulance rushed to the station and gave him medical attention before he was taken to the Mater Hospital.
Gardai are working on the theory that O'Neill was targeted by members of 'Fat' Freddie Thompson's gang.
They have also not ruled out involvement by a group of criminals in Newbridge, Co Kildare.
Investigators believe the attempted murder is linked to another failed assassination attempt on O' Neill last year.
At about 11pm on May 15 last year, O'Neill, from Sheriff Street, in Dublin's north inner city, had another lucky escape when he was shot as he sat in his Audi A4 outside Ruby Finnegan's pub in Ballyfermot.
On that occasion a bullet skimmed his chest and he also suffered a flesh wound to the shoulder.
He drove his Audi to the gates of nearby Cloverhill Prison for help, arriving there shortly before 11.30pm.
He told prison officers he had been shot and was given emergency treatment at the prison.
After O' Neill arrived there, prison authorities notified gardai, who carried out a detailed investigation but made no arrests in relation to the incident.
