A former Fianna Fáil running mate of Brian Cowen has suffered minor injuries after shots were fired while he was leaving home with his family.
Gerard Killally, 42, was in his car with his father and two young sons when a gunman travelling in an Opel Astra opened fire.
They had just left his home in the townland of Shean, Edenderry, Co Offaly, at around 10.40am.
Killally managed to drive a short distance before he hit a ditch and the car overturned.
Nobody was injured in the gunfire but all four suffered minor injuries when the Volkswagen Passat crashed.
Gardaí are hunting the silver-coloured Astra saloon, with a 06-D registration plate. They have appealed for witnesses.
Killally, a former Cathaoirleach of Offaly County Council, received a suspended three-year prison sentence last year after he pleaded guilty to stealing €18,000 of equipment from a shop he used to own in Rochfortbridge, Westmeath.
The bankrupt father-of-four was also handed 240 hours of community service for a fraud offence.
Killally, an auctioneer and developer who ran in the 2002 general election alongside ex-taoiseach Brian Cowen, has been at the centre of a number of court cases in recent years.
In 2010, bankruptcy documents put his debts at more than €73m.
A year later, a man was charged with stalking him and he was also before the courts over an alleged €10m land-scam deal.
Investigators have asked anyone who was in the vicinity of Shean between the hours of 9.30am and 10.40am this morning to get in contact with them.
Anyone who saw either cars involved in the incident have also been asked to come forward.
