LONDON -- Police in the southern German city of Munich said the famous Oktoberfest event would be closed until Wednesday afternoon, following a bomb threat linked to a deadly fire at a home in the north of the city.

"Due to a bomb threat in connection with the explosion in northern Munich, the Theresienwiese will remain closed until 5:00 p.m.," Munich police said in a statement, referring to the open area west of the city center where the festival is located. 

"A letter from the perpetrator has been sent to this effect," police said. "A decision on further action will be made in the early afternoon."

The bomb threat was linked to a fire at a residential building that killed one person in northern Munich on Wednesday morning, authorities said.

Police and fire department personnel were dispatched to the scene in the Lerchenau area. Police said there was a "burning residential building" and there they had received reports of "loud bangs."

"According to current information, the residential building was deliberately set on fire during a family dispute," police said. "The injured person found has since died. Another person is missing and poses no danger."

Police later said they discovered "explosive devices" in the building. "Special forces have been called in to defuse the bombs," the police said.
