the bell was probably nagging him all day

A man threatening to blow up the Liberty Bell was detained Saturday, police said, after leaving two backpacks that he said contained explosives.

Police investigated and found no explosives.

The man, who has not been identified, is expected to be charged, said police spokeswoman Christine O'Brien.

Park rangers earlier Saturday morning stopped the unidentified male, who police said was threatening to blow up the Liberty Bell. The man also said he had explosives in his backpacks, O'Brien said.

Two black backpacks were found in front of the Liberty Wheels wheelchair and scooter rental shop at 714 Market Street.

Police arrived on the scene at approximately 10:45 a.m. and closed off Market Street between 7th and 8th Streets, blocking off car and foot traffic.
