A crazed bit actor wielding an ornate Freemason sword hacked his mother to death early Tuesday in their New York apartment while screaming out Bible passages and Masonic references, police and witnesses said.

"Repent! Repent! Repent!" Michael Brea, screamed at his 55-year-old mother, Yannick, during his bizarre meltdown and the subsequent bloodbath at their Brooklyn, N.Y., apartment, neighbors said.

Brea, 31, who had roles in "Ugly Betty" and the movie "Step Up 3D," was heard repeatedly through the door shouting about the "architect of the universe," a term used by Freemasons to refer to a supreme being. Longtime family friend Sylvan Benoit confirmed that Brea was a member of the Freemasons and had been to a meeting earlier in the evening.

The Masonic sword was 3-feet long and meant for ceremonial use, police sources said.

When cops broke down the apartment door at around 2 a.m., they Tasered and arrested Brea, and charged him with murder.

He was taken to Bellevue Hospital for psychiatric evaluation, and allegedly blurted out, "When I looked at my mother, I saw the devil."
