LEWISTON — Five local men were arrested Wednesday on warrants charging they were selling crack cocaine, police said.

Local police and state drug agents conducted a six-month undercover investigation that included purchases of crack from the five men at various locations around the city, resulting in their arrests. The investigation is ongoing and more arrests are expected, police said Thursday.

Police arrested:

• James Earl Pontoo, 34, on four counts of aggravated trafficking in crack. He has a trafficking in controlled substances conviction from 2004 in Worcester, Massachusetts.

• Shane Daniel Pontoo, 30, for unlawful trafficking of crack and unlawful furnishing of crack.

• Cain Roberston, 26, for aggravated trafficking of crack and a probation hold.

• Timothy Joseph Rodrigue, 53, for unlawful trafficking of crack.

• Christopher “CJ” McFarland, 43, for aggravated trafficking of crack. He has a 2016 conviction in Androscoggin County for trafficking in scheduled drugs.

Agents and police searched a home at 101 Pine St. where they seized items connected to drug-trafficking, police said.

All of the men were taken to Androscoggin County Jail in Auburn. Cash bail for James Pontoo was set at $10,000, for Shane Pontoo, $2,500, for Robertson, $5,000, for Rodrigue, $2,500 and for McFarland, $5,000. Both Pontoos have posted bail and were released. The other three were scheduled to appear in 8th District Court on Friday for initial appearances.
