BROWNSVILLE, Texas (AP) - A 19-year-old Brownsville man is jailed on a drug charge after he allegedly went door-to-door trying to sell marijuana.

A Brownsville police spokesman says Anthony Carrazco's alleged scheme went awry when he knocked on a police officer's apartment door.

Spokesman Jimmy Manrrique says the episode happened Thursday downtown near the University of Texas-Texas Southmost College campus. He says Carrazco appeared to be intoxicated and allegedly had three ounces of marijuana with him that he tried to sell door-to-door.

Finally, Carrazco knocked on the off-duty police officer's door. The officer "said he would be right back and went to get his badge and handcuffs."

Manrrique says the officer, whose identity was withheld, also found a handgun hidden on the man. Carrazco remains in a Cameron County jail with bonds totaling $10,000. No attorney was listed in his booking record.
