A man threatening to blow up the Liberty Bell was detained Saturday, police said, after leaving two backpacks nearby that he said contained explosives.
Police investigated and found no explosives.
The man was expected to be charged, Officer Christine O'Brien, a spokeswoman for the Philadelphia Police Department, said Saturday evening. He had not been identified as of late Saturday night.
A police source said the man was not from the Philadelphia area and did not appear to have a criminal record.
Sometime before 10:45 a.m., National Park Service rangers stopped the man Saturday morning, after reports that he was threatening to blow up the Liberty Bell. The man also said he had explosives in his backpacks, O'Brien said.
