The police found no evidence of a shooter or any injuries at Capitol Hill, Washington Metropolitan Police Department Spokesperson Hugh Carew said Wednesday after receiving a report of a possible active shooter in the Capitol complex on Wednesday. The report was blamed on a false alarm or a "bad call".

The US Capitol Police earlier asked people in the Senate office buildings to seek shelter as a precautionary measure.

While the Senate was in summer recess, some staff members were still present, along with workers in cafeterias, security posts, and tourists visiting the Capitol.

Although the Capitol building itself was not under a complete lockdown, police advised all workers to remain in their offices until the situation was resolved. The police did not receive any confirmed reports of gunshots.

In response to the emergency call, the Capitol Police instructed people to move into their offices, take necessary emergency equipment, and silence their electronic devices to maintain quiet.

The Police had issued an alert earlier in the day about a potential active shooter at the US Capitol.

"If you are inside the Senate Buildings, everyone inside should be sheltering in place as the report was for a possible active shooter. It should be noted that we do not have any confirmed reports of gunshots," the US Capitol Police said in a post on social media.

The police said they were responding to an emergency call as they dispatch to the site.
