'Ugly Betty' Actor Eric Mabius Arrested for Battery

1:35 PM PT -- TMZ has obtained the arrest report ... A Nassau County sheriff's deputy responded to a call about a fight at a bar in the city of Yulee, Florida at about 2:13 Thursday morning. The deputy says a male at the scene was trying to help a woman stand just inside the doorway ... and both appeared "extremely intoxicated," yelling at people inside. The deputy and a second deputy carried the woman outside, where she laid on the ground, and "continued to resist," according to the report.

The deputy said the bartender and other patrons had told the woman she was being obnoxious and asked her to leave ... and that's when the woman spat on several people ... then Eric Mabius allegedly pushed her and another woman to the ground. Eric then got on top of this second woman and pulled her hair, allegedly ripping a handful from her scalp. People in the bar then separated them.

When deputies arrived, Eric allegedly became belligerent and refused commands to sit, even walking up behind one deputy ... prompting his arrest. Mabius and the drunk woman were both arrested for battery and resisting without violence.
