Acting on the "probable cause" feature of high court rulings, Federal prohibition agents yesterday halted a sedan operated by a man who gave the name of James Wilson, and placed him under arrest when they found sixty gallons of asserted alcohol and half a gallon of asserted whisky in the vehicle.
    At the Federal Building the prisoner was recognized as John H. Wyncoop, a former Federal prohibition agent, who served a sentence of a year and a day in the McNeil Island Prison for illegal conversion of whisky said to have been stolen from the government warehouse in 1926. Wyncoop and other agents found the liquor hidden in a barn in the vicinity of Long Beach and divided most of it among themselves. He was arrested as he was in the act of driving his sedan into a private garage at North Hill and California streets.
    Taken before United States Commissioner Head the prisoner furnished a bond of $500 for his release, pending a hearing the 29th inst.
    Another arrest of yesterday was that of Ralph Bierce in Hawthorne. He was charged with transporting two gallons of asserted liquor in his motor car. He was unable to furnish bail.
