It's unclear if the account was suspended by Twitter or deactivated by Assange himself.
An account, which claimed to be Assange's alternative account, stated that Twitter had deleted his official one ahead of a 'bombshell' story he's preparing to break, reported the Independent.
However, there was no clear sign that the 46-year-old Assange was behind the alternative account and it was also later suspended by Twitter.
The Australian computer programmer's brief Twitter disappearance received mixed responses from the public. While some of Assange's supporters expressed anger for they believed it to be 'Twitter's censorship of free speech', others hailed that the account 'could no longer be viewed', the report said.
