Washington (CNN) -- Several streets in Washington were closed Wednesday morning as authorities investigated a report of a suspicious package, officials said. A police spokesperson later said no hazardous material was detected.
The focus of police attention appeared to be a hoax device that looked like a long microphone with tape on it, a law enforcement source said. It also could have looked like a pipe, the source said.
A terrorism task force will study it, the official said.
"No hazardous material has been found," said Gwen Crump, a Metropolitan Police Department spokeswoman. "We are continuing to examine it."
Police received a report about the device about 7:45 a.m., Crump said. Streets were being reopened around 1:15 p.m.
Authorities were summoned to investigate the package, which was left near a building that houses employees of the General Services Administration, said Sahar Wali, a spokeswoman for the agency.
The Department of the Interior closed the E Street entrance to one of its buildings in response, said Kendra Barkoff of the Interior Department, which notified employees of the situation in an e-mail.
"There is a police emergency at the GSA building," the message said. It advised certain employees to "leave their offices and close the doors."
