Austin police arrested a 30-year-old homeless man after finding him nude and harassing a man and elderly woman near the University of Texas campus on Saturday.

Nathan Pearson allegedly grabbed a 66-year-old woman and put her in a "bear hug" as she walked through an alley to her car from the Church of Scientology on Guadalupe Street, according to an arrest affidavit.

The woman told police that her nose and mouth were pressed up against Pearson's chest so tightly that she was unable to breathe for one minute, the affidavit said. She also got Pearson's sweat in her mouth.

Pearson repeatedly called the woman "grandma," who was able to position her face in a manner that allowed her to breathe.

Pearson eventually let the woman go and proceeded to grab another man in the alley from behind and began "humping him," according to the affidavit.

After an officer arrived on the scene and threatened to use his stun gun on Pearson, the suspect jumped onto the man's back, grabbed him around the neck as if he was riding "piggyback" and "continued to hump him from behind," the affidavit said.

The officer used the stun gun on Pearson, who fell to the ground and was placed in handcuffs, the affidavit said.

Police suspected that Pearson was on some kind of medication or drug and said he displayed "a strength that seemed unnatural."

Officers also noted that Pearson was "rambling on in an incoherent babble and would randomly shout that he was Buzz Lightyear," according to the affidavit.

Pearson has also been charged with assault by contact, public intoxication and disorderly conduct. He is currently being held in Travis County Jail on a $25,000 bond.
