Maine State Police announced the arrest of 14 people on drug charges as part of a crackdown last week on drugs being imported into the state.

The arrests included four people charged with bringing drugs into the state on commercial buses. The four, who police believe were not known to each other, were arrested at the Portland’s Greyhound and Concord Trailways bus stations, police said in a statement.

Police charged:

- Hasan Daily, 21, of Cambridge, Mass., with possession of crack cocaine. Police said Daily also had a loaded .22 caliber handgun.

- Jermaine Mitchell, 40, of New Haven, Conn., with trafficking in crack cocaine and ecstasy.

- Isaiah Sapp, 28, of Bronx, New York, with trafficking in cocaine.

- Cyrus Martin, 43, of Lewiston, with trafficking in suboxone. Police said troopers seized 900 suboxone strips from Martin.

The others arrested were charged with less serious crimes, police said. In all, $32,000 in drugs were seized, they said.

The arrests occurred during 48 hours on Wednesday and Thursday.

Colonel Robert Williams, chief of the Maine State Police, said troopers including members of the Commercial Vehicle Enforcement unit will continue working to intercept drugs destined for sale in Maine.
