US Capitol Building on lockdown after reports of shots fired

DEVELOPING: Authorities responded Saturday to reports of shots fired on the West Front of the U.S. Capitol Building, prompting the entire building to be placed on lockdown, sources tell Fox News.
The suspected shooter has been "neutralized" and the lockdown was considered precautionary. Police also were investigating reports of a suspicious package near the scene of the shooting. 
Police said the shooting appeared to be a suicide, the AP said.
MyFoxDC reported that the suspected gunman was "disarmed and deceased."
"U.S. Capitol Police are locking down the U.S. Capitol Building and the Capitol Visitor Center due to a potential security threat," Capitol Police spokeswoman Kimberly Schneider said. "No one will be allowed to enter or exit the U.S. Capitol Building and the Capitol Visitors Center."
She also said Capitol Police were investigating a suspicious package on the lower west terrace of the building.
Congress has been on spring break for two weeks and lawmakers are set to return to work Monday.
