MIAMI (AP) - Miami's police chief is disputing reports of tension between his department and Florida Highway Patrol.
    
Last month, an FHP trooper arrested a Miami police officer at gunpoint for allegedly speeding to his off-duty job. Since then, law enforcement blogs have speculated about growing animosity between the agencies.
    
On Tuesday, Miami police say an officer stopped an FHP trooper on a turnpike extension outside city limits.
    
Interim Miami Police Chief Manuel Orosa said Thursday that the officer had no jurisdictional authority for that traffic stop. He says it's an isolated incident and the officer was disciplined.
    
Orosa says Miami police and FHP have a "professional, cordial relationship." He also has forbidden traffic stops of law enforcement vehicles without confirmation that a felony has been committed and approval from a commanding officer.
