A fit-challenged vandal dressed in red from head-to-toe flung ripped-up pages from the Quran at a Brooklyn mosque — then disgustingly smeared feces on the building, cops said.

The monochrome maniac unleashed the sickening attack on the Islamic Mission of America in Brooklyn Heights around 4:30 a.m. March 9 as the piggish perp threw the shredded pages on the mosque’s front steps, according to investigators.

The goofily dressed man returned a little while later and smeared excrement on the door of the house of worship, according to police.

The conspicuous crimson-clad creep then fled east on State Street, cops said.

Surveillance video showed the bearded fashion victim walking nonchalantly, swinging a small black plastic baggie, in a red sweatsuit with a black beanie rolled up around his head.

Cops said he also wore a black face mask.

The NYPD is investigating the unsanitary outburst as a hate crime.

The incident follows several other apparent anti-Muslim attacks in recent weeks.

A subway mugger last week threw a Muslim woman to the ground and taunted her over Mayor Zohran Mamdani, New York City’s first Muslim mayor.

“It’s funny how terrorists can walk around now,” the bigot snarled at the terrified 20-year-old woman.

In January, a 34-year-old woman went on a hate-filled rampage in the middle of the afternoon, assaulting two hijab-wearing women and randomly punching a 12-year-old girl in Bay Ridge Brooklyn, prosecutors said.
