Elon Musk is the new owner of Twitter

Billionaire entrepreneur Elon Musk closed the $44-billion Twitter deal on Thursday, becoming the new owner of the microblogging site.

He has also fired at least four top executives of Twitter, including its Indian-origin CEO Parag Agrawal.

Besides Agrawal, CFO Ned Segal, Head of Legal, Policy, and Trust Vijaya Gadde and General Counsel Sean Edgett have also been fired, reported Reuters.

The report added that at least one of the executives who was fired was escorted out of Twitter's office.

Agrawal's exit comes as an unsurprising move, considering how he and Musk had a public Twitter fallout a few months earlier and the latter accusing the outgoing CEO of misleading him and Twitter investors over the number of fake bots.

Agrawal was appointed Twitter CEO in November last year after the social media site's co-founder Jack Dorsey had stepped down.

An IIT Bombay and Stanford alumnus, Agrawal joined Twitter over a decade ago when there were fewer than 1,000 employees at the company.

Gadde was also singled out by Musk, accusing her of "left-wing bias" in content moderation decisions at the company. Gadde was also instrumental in the decision to suspend Donald Trump's account within days of the coup at Capitol Hill.

However, Twitter, Musk and the executives have not publically responded to the reports.

This comes as Musk walked into the headquarters in San Francisco on Wednesday in a dramatic fashion with a kitchen sink.

Earlier in the day, Musk also took to Twitter to explain why he decided to buy Twitter.

The closure of the deal comes after months of twists and turns after the Tesla CEO announced his intention to buy the social media giant for $44 billion and take the company private.

Musk had then said that he wanted to own and privatize Twitter because he thinks it was not living up to its potential as a platform for free speech.

However, he walked back on his word in July, opting out of the deal citing spam and fake accounts on the social media platform.

He also accused the company of refusing to give him information about its spam bot accounts.

It was then that Twitter sued Musk to force him to complete the deal.

The Musk-Twitter legal dispute went on trial in October, but during the trial, Musk decided to go through with his original proposal to buy Twitter for $44 billion.
