In September 2001, a man named Friedrich Leibacher went on a rampage in the regional parliament in the wealthy northern Swiss city of Zug, killing 14 people and himself, apparently over a grudge against a local official. The massacre, along with a campaign to reduce Switzerland's high level of gun suicide, led to a referendum last year. It proposed that military issued firearms must be locked in secure army depots and would have banned the sale of fully automatic weapons and pump action rifles.

UBS AG agreed Wednesday, Dec. 19, 2012 to pay some US$ 1.5 billion in fines to international regulators following a probe into the rigging of a key global interest rate. In admitting to fraud, Switzerland's largest bank became the second bank, after Britain's Barclays PLC, to settle over the rate rigging scandal. The fine, which will be paid to authorities in the U.S., Britain and Switzerland, also comes just over a week after HSBC PLC agreed to pay nearly US$ 2 billion for alleged money laundering.
