St. Mary Parish Sheriff's deputies are investigating after a man under arrest died in the back of a police car.
Deputies were called to a house in Patterson late Sunday night, a spokesman said.
They arrested Hector Ruiz-Santos, 42, on charges of battery on a police officer, resisting an officer with force and disturbing the peace.
When deputies got to the St. Mary Parish Law Enforcement Center to book Ruiz-Santos, they found him unresponsive. They tried CPR and an ambulance came, but life-saving efforts weren't successful, the spokesman said.
An investigation into this incident is ongoing. Further details will be released as they become available, the spokesman said.
