U.S. Capitol Police are investigating reports of possible sounds of gunfire in the parking garage of the Rayburn Office Building, where members of the House have their offices. Shots reportedly were heard by a single staff person, CNN Producer Ted Barrett reports. The Capitol has been reopened, but the House office building remains sealed. There has been no confirmation that the sounds heard were actually gunfire.

The Capitol complex was locked down on Friday following reports of the sound of gunfire.
WASHINGTON (CNN) -- Capitol Police said Friday they were investigating reports of sounds of gunfire in the garage of the Rayburn Office Building, where members of the House have their offices.
"They have no victims at this time, and they have no active shooter," said Mike Brooks, a law enforcement expert.
He noted that Capitol Police have a firing range in the basement, but a congressional source said the shots were not heard from that level.
Business continued as usual on the Senate side, CNN's Dana Bash said.
The Containment and Emergency Response Team was searching the area, Brooks said.
CNN's Kelli Arena reported that heavily armed officers were headed to the area.
The alert came moments after a press conference held by Rep. John Sensenbrenner on immigration reform, CNN producer Deidre Walsh said.
"We saw several Capitol Hill police officers running quickly down the hallway," she said. Soon after that an announcement was made throughout the building.
Rep. Peter Hoekstra, R-Michigan, was conducting a House Intelligence Committee hearing at the time.
Hoekstra interrupted a witness to tell those at the hearing to remain in the room and said doors must be closed.
"It's a little unsettling to get a Blackberry message put in front of you that says there's gunfire in the building," he said.
"They said they heard gunfire in the Rayburn garage, but this is a huge building, I'm guessing it's a car backfiring or balloons popping," Gene Smith, chief of staff to Rep. Howard Berman, D-California, told The Associated Press. Berman has an office in Rayburn.
