Insisting that his agency's relationship with the Florida Highway Patrol is not strained, Miami's police chief on Thursday issued a formal warning to an officer who pulled over a trooper on the turnpike.

Miami Interim Police Chief Manuel Orosa also tightened the department's policy for pulling over fellow law enforcement officers, mandating no traffic stops without approval from a supervisor and only if the targeted officer is engaged in a felony.

The measure came two days after Miami police officer Thomas Vokaty pulled over a uniformed FHP trooper on the turnpike at Okeechobee Road despite "not having jurisdictional authority," according to a discipline report released Thursday.
