BATON ROUGE - A man died from a medical episode near Navajo Street and Scenic Highway across from the Exxon Mobil Baton Rouge Chemical Plant Friday morning.

Darrel Thomas, 43, was first seen laying in the driveway in front of the Exxon plant entrance gate when a security detail called EMS. 

Emergency crews say that Thomas appeared to be stable and calmed down when they left the scene. 

Authorities told WBRZ that moments after EMS left Thomas was seen running in and out of traffic when a security detail of off-duty law enforcement at Exxon handcuffed and detained Thomas and then called EMS. 

They went on to say the man was detained on the side of the road awaiting transportation to the hospital when he suffered from some sort of medical episode.

The East Baton Rouge Parish Coroner's Office said the cause and manner of Thomas' death will likely be known following an autopsy Monday.
