The badass Samoan guy on "Deadliest Catch
" is in trouble for allegedly squeezin' one out in a men's room in Alaska ... as in, he's been accused of putting some guy in a serious headlock.
TMZ has learned ... Feleti "Freddy" Maugatai
has been charged with misdemeanor assault over a violent altercation at the Grand Aleutian Hotel in Alaska on December 16.
According to the criminal complaint obtained by TMZ ... a female witness claims the Discovery Channel reality star got into a fight with her husband ... and it spilled over into the restroom.
When the woman went to check on the situation, she claims she observed that Freddy had her husband in a headlock.
The woman claims she tried to free her hubby, but Freddy grabbed her by the arm and "forcefully" pushed her across the restroom.
When cops arrived to the scene, police say they observed the woman had bruising and swelling on her arm.
According to the complaint, Freddy told police he didn't start the fight ... but was merely defending himself after the other man punched him in the face. Freddy says he "did not touch Katz."
A few days later, a judge ordered Freddy to stay away from the woman, her husband and the hotel. He's due back in court later this month.
TMZ attempted to reach Freddy for comment -- but he's currently working on the F/V Wizard crab boat in Alaska. A rep for Discovery had no comment.
