A couple is recovering after they were savagely beaten by a 300-pound naked bodybuilder in a bizarre encounter outside their home. Hit the jump to read the rest of the story.

Ruben Arzu, 22, was waiting on the unidentified couple’s front porch when they returned to their home in Colton, Calif., at around 11:30 p.m. on Saturday, The San Bernardino Sun reported.

When the 34-year-old woman fled inside to call police, the nude brute attacked her husband, 35, “causing major head trauma and injuries,” police told the newspaper.

When the man’s wife tried to stop the beating, Arzu went after her, tossing her around like a rag doll and splitting open her head, police said.

Arzu took off after the attack, but neighbors cornered him in the backyard of another home, the Sun said.

Cops said it took four officers and multiple jolts from a Taser gun to finally take the muscle-bound thug down.

Arzu was booked for attempted homicide.

The couple was reported in stable condition at Arrowhead Regional Medical Center on Monday.

Police didn’t say what started the beef, but they suspected Arzu was juiced up on steroids and other drugs.

“It’s a good thing our officers arrived on scene so quickly, because who knows who was next,” said Colton police spokesman Cpl. Ray Mendez told the Sun.
