A gunman opened fire Monday in the offices of a bank where he worked, fatally injuring two people before turning the weapon on himself, police said.

The 56-year-old financial adviser entered the offices of the Zuercher Kantonalbank (search) in central Zurich early Monday and fired several times at the chief of financial planning and the bank's head of financial advice, police spokesman Marco Cortesi said. The man then shot himself.

The two victims, aged 45 and 41, were seriously injured in the attack and were taken to a hospital. Both died in the afternoon, the bank said.

Police sealed the area and evacuated about 80 employees from the building after receiving an emergency call about 8 a.m.

They discovered the two victims, but initially found no trace of the gunman. They later found him dead in his office on another floor.

The bank said it was "deeply shocked," calling the shooting "incomprehensible."

Bank officials said the gunman had given no previous cause for concern. Police said that the motive apparently was a workplace dispute.

In 2001, a man with a grudge against officials killed 14 people before shooting himself to death inside the local parliament of Zug (search), south of Zurich, shocking the low-crime country.
