A 25-year-old bank employee arrested in connection with the state's biggest bank robbery was released without charge yesterday.

The Bank of Ireland worker had been questioned in Naas since Thursday over the €7m heist at the bank's College Green, Dublin, branch last February. An armed gang targeted a bank worker, his girlfriend, her mother and six-year-old nephew in a tiger kidnapping. An organised crime gang in Dublin was blamed.

Employee Shane Travers, from the north of the city, was forced at gunpoint to drive to work and show a photograph of the kidnap to work colleagues before filling laundry bags with cash from the vaults.
