An enraged company executive tried to "strangle" a cyclist with his helmet straps after shouldering him off his bike because he was riding on the footpath.
David Corcoran (51) was out walking near his office on a south Dublin street when he attacked the cyclist in an over-reaction to what a court heard was a "minor nuisance".
Corcoran had been "under a bit of stress" when he knocked the man off his bike, punched him and kneed him while he had him in a headlock.
Judge Michael Walsh ordered him to pay €3,130 compensation to the victim for dental injuries he suffered in the attack.
Adjourning the case, he also told the accused to make a €2,500 donation to charity and said he would strike the case out, leaving him with no criminal record.
Corcoran, of Collinswood, Whitehall, admitted assault causing harm to Philip Fitzgerald.
Dublin District Court heard the incident happened at Clanwilliam Terrace on July 1 last year.
Mr Fitzgerald was cycling towards Corcoran at 10.30am when the accused shouldered him off his bicycle, causing him to fall to the ground.
Gda Brian Cleary said Corcoran punched him in the head and face before getting him in a headlock, causing him to be choked by the straps on his bicycle helmet.
He then kneed Mr Fitzgerald while he was in the headlock. Members of the public intervened and broke it up.
The victim had made a full recovery.
Corcoran, who had no previous convictions, had been walking near where he worked and there was a van parked on the footpath, his solicitor Eugene Dunne said.
Instead of stepping aside, he leaned in towards the cyclist, who came off his bike and a confrontation then took place.
There was a problem with people cycling on the footpath, which had happened several times, said Mr Dunne.
Corcoran accepted that he over-reacted.
He caught the cyclist, struggled with him and held on to his helmet, said the solicitor.
"He went further than that, he used the straps to try to strangle him," said Judge Walsh.
Mr Dunne said the straps had been under Mr Fitzgerald's chin during the incident.
"It's effective strangulation," the judge said.
He added that the accused had seen the victim from 20 feet away
Of people cycling on footpaths, the judge said: "We live in a somewhat congested city and sometimes needs must."
Mr Dunne replied: "He should have stepped aside but, to be fair, the other party shouldn't have been cycling on the footpath."
Judge Walsh said the acc-used's response was disproportionate to what had been "no more than a very temporary, minor nuisance".
Mr Dunne said there had been no premeditation.
