Elon Musk posted video showing him strolling into Twitter headquarters ahead of a deadline to close his $44 billion deal to buy the company.
Musk also changed his Twitter profile to refer to himself as “Chief Twit” and his location as Twitter headquarters, which is based in San Francisco. The video showed him carrying a sink through a lobby area.
“Entering Twitter HQ - let that sink in!” he tweeted.
A court has given Musk until Friday to close his April agreement to acquire the company after he earlier tried to back out of the deal.
Neither Musk nor Twitter has said if the deal is closed yet.
Despite Musk's splashy entry to headquarters, it wasn't clear yet whether his purchase of Twitter had been finalised.
Twitter confirmed that Musk's video tweet was real but wouldn't comment further.
