German police closed the Oktoberfest fairgrounds Wednesday morning following a bomb threat from the suspected perpetrator of an explosion in northern Munich, city officials said.

At least one person’s death was believed to be connected to the explosion at a residential building early Wednesday, which Munich police said was deliberately set on fire and part of a domestic dispute.

Officials discovered the bomb threat to Oktoberfest in a letter from the alleged perpetrator. Police searched the fairgrounds for other explosive devices and asked workers to leave the area. Authorities said the festival will be closed at least until 5 p.m. local time (1500 GMT) Wednesday.

This year’s Oktoberfest began on Sept. 20 and ends Oct. 5. The world’s largest beer festival usually attracts up to 6 million visitors.

In 1980, Oktoberfest was the target of a deadly neo-Nazi attack. The bombing on the evening of Sept. 26, 1980 claimed 13 lives, including that of three children and the attacker, student Gundolf Koehler, a supporter of a banned far-right group. More than 200 people were wounded.
