MIAMI (CBSMiami) —  A man who troopers say jumped on the hood of a moving car on the Palmetto Expressway remains in custody.

Florida Highway Patrol said the man had a knife in his mouth during the bizarre incident Tuesday evening.

Troopers say the man was trying to flag people down for help after his vehicle broke down on the side of the Palmetto Expressway (SR-826) around 9 p.m.

At some point, he ended up jumping on the hood of a white Mercedes driven by a woman near NW 67th Avenue.

The woman who was terrified during the situation kept driving down the Palmetto until she spotted an off-duty trooper near NW 57th Avenue and ran to him for help.

The trooper ended up using a Taser on the man after a brief exchange.

“The trooper in this case, you know, felt that his life was threatened, but he did what he is trained to do. And he used a less deadly method. In this case he used his Taser.  And he was able to get the subject under control, arrested the subject,” said Florida Highway Patrol Joe Sanchez.

Troopers believe the man was either on drugs or had some sort of mental issue. He has since been Baker Acted.

Authorities have not released the man’s identity. Charges remain pending.

The incident locked up part of the Palmetto Expressway during the investigation.
