Moment US Air National Guardsman Jack Teixeira arrested by FBI amid probe into leak of top-secret Pentagon docs

THIS is the moment US Air National Guardsman Jack Teixeira was arrested by FBI agents investigating the top-secret Pentagon files leak.

Jack Teixeira, 21, has been taken into custody after he was detained in Dighton, Massachusetts.

News helicopter footage showed the suspect - in red shorts with his hands behind his back - being placed by heavily-armed agents into an unmarked sports utility vehicle, in a forested area.

US Attorney General Merrick Garland said Teixeira was arrested "without incident" and he will have an initial appearance in court.

Jack Teixeira is a 21-year-old national guardsman with the Massachusetts Air National Guard.

Jack is enlisted in the 102nd Intelligence Wing of the Massachusetts Air National Guard.

He serves as a member of the intelligence wing and his identity was first reported by .

Teixeira allegedly oversaw an online Discord group called Thug Shaker Central where approximately 30 people - mostly young men and teens - shared a love of guns, racist memes, and games.

The group is allegedly responsible for leaking the documents.

The leaked documents, which were shared on Discord, Twitter, and Telegram, contain sensitive information about the support the United States is providing Ukraine amid its war with Russia.

The classified documents contained details of US and Nato plans to help Ukraine prepare ahead of a spring offensive against Russia.

They reportedly contained sensitive information including charts and details about weapons deliveries, and battalion strengths.

In what can be considered one of the worst intelligence breaches in US history, the leak fuelled the fire of speculation about Vladimir Putin's health amid rumours he is battling cancer.

The docs suggested that the Russian leader is undergoing chemotherapy while his inner circle could be using his deteriorating health to plot against him.

The leaked military documents showed that a British spy plane narrowly avoided being shot down by the Russians due to a missile malfunction.

According to the report, the Russian jet was flying above the Black Sea when its pilot believed he had permission to fire.

Fortunately, the missile malfunctioned and a potentially catastrophic incident was averted.

The docs also included information about China, suggesting that Beijing has secretly launched a 6,500mph hypersonic missile that could beat US defence systems.

One of China's experimental missiles, the DF-27 hypersonic glide vehicle, was launched on February 25 and flew for 12 minutes over a distance of 1,300 miles.
