DALLAS A Dallas police officer was fired by Chief David Brown on Tuesday after failing a drug test.

In a written statement, police said Officer Rashad Davis tested positive for marijuana use last month.

Davis also allegedly violated the department's administrative leave policy and failed to cooperate in an internal affairs investigation.

Police said there were three additional investigations pending against Davis.

The terminated officer had been on the force for four years and was assigned to the South Central Patrol Division.

Police said Davis has a right to appeal for his job.
