The allegedly serial-spitting drug suspect forced to wear a Hannibal Lecter-like mask in court was acquitted in a feces-flinging case Monday.

As he sat in an upstate Warren County courtroom and heard the “not guilty” verdict read aloud, defendant Tyson Poulos’ joy could be seen through the top mesh portion of his spit shield, said his lawyer, Norm Steiner.

“His eyes portrayed a moment of restored humanity,” Steiner told The Post.

“He asked me to make sure I thanked the jurors for giving him a chance, despite how he looked.”

In Monday’s case, Poulos, 33, had been accused of splashing correctional officers with urine and splattering them with feces while in prison on a 32-year sentence for peddling heroin. He was convicted of the foul raps and sentenced to another five to 10 years for them.

But he appealed both his drug and officer-harassment convictions — and won.

He was just retried on the alleged attack on the guards and acquitted, after his lawyer argued his client had been going through serious drug withdrawal and was being ignored by the officers at the time, so he was forced to take extreme action — flinging the excrement.

Poulos is still in jail awaiting a retrial on the drug charges.

During his drug trial, which began in 2014, he was accused of spitting on two different lawyers and was eventually ordered by a judge to wear the mask.

Last week, Steiner tried unsuccessfully to get the judge to lift the mask restriction during his client’s retrial on the feces-throwing.
