A TSA worker in Miami was arrested when he "lost his mind" and attacked a colleague who repeatedly made fun of his small penis after the security screener walked through a high-tech scanner that showed his genitalia, according to Miami-Dade police.

Rolando Negrin, 44, was arrested at Miami International Airport Wednesday morning following an altercation with a fellow screener, Hugh Osorno, Tuesday evening. Negrin is facing assault charges for allegedly beating Osorno with a baton in the airport's parking lot, NBC Miami reported.

Negrin had been embarrassed and enraged by constant ribbing from his colleagues after a training session with a "Whole Body Imaging" machine, according to the police affidavit.

"The X-ray revealed [Negrin] has a small penis and co-workers made fun of him on a daily basis," according to the report.

Negrin showed up for work as usual Wednesday and can be seen in the uniform blue shirt and epaulets of the TSA in his booking photo. Osorno suffered abrasions on his back and arms from the attack, police said.
