SACO — A Saco man was charged Wednesday with trafficking in heroin after an investigation into suspected drug activity at 125 Lincoln St.

Michael A. Constible, 23, is being held without bail at York County Jail.

Constible initially drew the attention of police Tuesday when he was arrested in Biddeford on an outstanding warrant. At the time he was carrying 1 gram of heroin, said Saco Deputy Police Chief Jeffrey Holland.

After that arrest, Maine Drug Enforcement agents and Saco police made contact with three residents in apartment No. 6 at 125 Lincoln St. A search of the apartment turned up 8.4 grams of heroin stored in a bedroom, Holland said.

The heroin was pre-packaged for sale in 18 individual plastic baggies. The estimated street value of the heroin is $1,350, according to police.
