The manic Manhattan college professor who threatened a Post reporter with a machete has been fired, the school said Tuesday — as it emerged she is suing the NYPD for allegedly abusing her during the 2020 George Floyd protests.

Shellyne Rodriguez was sacked by Hunter College just hours after the adjunct professor was caught on camera holding the blade to the veteran reporter’s neck while threatening to “chop” him up outside her Bronx apartment.

“Hunter College strongly condemns the unacceptable actions of Shellyne Rodriguez and has taken immediate action,” Hunter College spokesman Vince Dimiceli told The Post.

“Rodriguez has been relieved of her duties at Hunter College effective immediately, and will not be returning to teach at the school.”

The unhinged art professor wielded the machete and spewed the menacing remarks after the veteran Postie approached her regarding a viral video that showed her flipping out on pro-life students at Hunter College earlier this month.

In other developments, it also emerged Rodriguez is currently embroiled in a legal saga against the NYPD over allegations officers abused her when she arrested during the George Floyd protests in June 2020.

Rodriguez, who is the lead plaintiff in the lawsuit, claims she suffered nerve damage from being zip-tied when she was nabbed and put in a prisoner van with other protesters.
