The Orleans Parish Crime Sheriff's Office says a man who was being booked into the parish prison died Saturday from apparent natural causes.

Mary Martin, a spokeswoman for Criminal Sheriff Marlin Gusman, said Sunday the man, whose name is being withheld until relatives can be notified, was arrested Friday on multiple warrants from Orleans and Jefferson parishes.

On Saturday, about 7:30 a.m., he collapsed in a restroom at the intake and processing center.

Martin said paramedics declared him dead at the scene shortly before 8 a.m.

Martin said the coroner is conducting a full autopsy with toxicology testing.
