After a year of bombshells, it was a bomb threat that made headlines at city hall on Monday.

Mayor Rob Ford said someone threatened to blow up city hall if he doesn’t resign from office. Ford told reporters that the threat came in an email Monday to his brother, Coun. Doug Ford.

“They mention my name, that if I don’t resign immediately the building is going to get blown up,” Ford said at city hall.

“I don’t want people to panic,” he continued. “The police are working on this as fast as possible to find out who sent it, and from what I understand the dogs are coming in to sweep the building.”

Police confirm they received a call about the threat on Monday morning, but no evacuations were ordered after police dogs failed to sniff out anything suspicious.

“Certain parts of the building were checked…and we found no evidence to support any threat to the public or to the people that work here,” said Insp. Frank Barredo.

Police said they received a call about the letter at 10:50 a.m.

Ford said police did not direct him to publicly announce the threat, but that he decided to do so to “inform the public.”

Bomb threats like these have been made before but are usually not made public.

The mayor said the letter was also sent to the city manager’s office.

“All I can say is there were no bombs in my office or my brother’s office, or the deputy mayor’s office…I want to thank the police for a great job,” Ford said.
