Elon Musk completes $44bn Twitter takeover

The world's richest man, Elon Musk, has completed his $44bn (£38.1bn) takeover of Twitter, according to US media and an investor in the firm.

He tweeted "the bird is freed," in an apparent reference to the deal closing.

A number of top executives, including the boss, Parag Agrawal, have reportedly been fired.

It brings to a close a saga that saw Twitter go to court to hold the multi-billionaire to the terms of a takeover deal that he had tried to escape.

Twitter has not yet confirmed the takeover, but an early investor in the company said that the deal had been completed.
