Facebook has shut down its account with the FBI for suspected cyber attacks.
The social media giant announced on Tuesday that it had received an “advisory” for “malicious activity” and would not be using its account in the future.
It was not immediately clear why Facebook decided to close the account.
Facebook says it was a result of “continued law enforcement investigations”.
The FBI said on Twitter that it was “working with Facebook on a review of our investigations”.
“Facebook’s continued use of its Twitter account for criminal activity is a serious threat to our nation’s security and undermines our ability to share information securely and openly,” FBI Assistant Director-in-Charge David Bowdich said in a statement.
“We encourage Facebook to close their Twitter account immediately.”
The account has had about 5.5 million followers since it was launched in 2014.
Facebook has been under investigation since December after it was revealed that hackers were able to break into accounts belonging to at least four of its US employees.
Facebook said on Wednesday that it would be changing the way it uses its Twitter accounts to protect its users.
“As we’ve been able to make this change, we’re not going to use Facebook as a way to target anyone.
We’re going to be using the account to provide a safe platform for our users,” Facebook’s head of international marketing Ben Veiga said.
“When a criminal actor tries to use a Twitter account to conduct criminal activity, we’ve made it very clear that it’s illegal, and we will not use it for that purpose.”
