NEW YORK (AP) -- The medical examiner's office says it's still trying to determine what caused the death of a New York City man who appeared to be held in a chokehold as police attempted to arrest him.
The office says in a statement that the "cause and manner" of Eric Garner's death are pending further studies.
Meanwhile, the fire department has barred four emergency workers from responding to 911 calls. They are employees of the Staten Island hospital where Garner was pronounced dead on Thursday.
The medics' restricted duties will remain in effect pending an investigation into their actions.
The fire department took the action after a second video surfaced showing some half-dozen officers and emergency workers circling a man who appears to be Garner lying on the sidewalk, handcuffed and unresponsive.
