A Biddeford man is being held on $10,000 bail after police allegedly found 49 grams of cocaine in his shoes following a field sobriety test.

Maine State Police charged Mason Soto, 26, with trafficking in cocaine following a traffic stop in the northbound lanes of the Maine Turnpike in Augusta just after midnight Tuesday.

Trooper Kristy Libritz stopped Soto for allegedly driving erratically. During a field sobriety test, Soto also was walking erratically and Libritz said she found a ball of 21 grams of cocaine in one of Soto’s shoes.

He was taken to York County Jail in Alfred where another ball with additional cocaine was found in the other shoe, police said.
