San Francisco, Jun 1 (IANS): After hacker group Anonymous issued a threat of retribution for the death of George Floyd allegedly due to police brutality, the website of Minneapolis Police Department showed signs that it faced a cyber attack.

The website currently requires visitors to submit "captchas" to verify they are humans, not bots, the New York Post reported on Monday.

On its unconfirmed Facebook page on Thursday, hacker group Anonymous said it was targeting the department.

The politically-charged hacker group targeted the police department for its "horrific track record of violence and corruption" in an almost four-minute video.

"This travesty has gone on for far too long, and now the people have had enough," a figure said in a mechanical voice.

"People have had enough of this corruption and violence from an organization that promises to keep them safe," it added.

"Unfortunately, we do not trust your corrupt organization to carry out justice, so we will be exposing your many crimes to the world," said the masked figure.

Some 5,000 US National Guard troops were deployed in major states amid the ongoing protests against the death of Floyd in police custody on May 25 in the city of Minneapolis, while also demanding an end to racism and police violence.
