Police arrested one man and charged another during an earlym orning drug bust that yielded up to $20,000 worth of cocaine today on U.S. Route 1.

Acting on a motorist’s complaint of a vehicle with Mass- achusetts plates “behaving erratically,” Brunswick patrol Officer Matthew Swan stopped the car near the bike path at 3:17 a.m. today, according to Deputy Chief Marc Hagan.

Swan became suspicious while questioning the men and, during a subsequent search, found 168 grams of cocaine taped to the inner thigh of the car’s front-seat passenger.

Hector Nieves-Martinez, 19, of 153 Belleville Ave., New Bedford, Mass., was charged with aggravated trafficking of scheduled drugs. His bail was set at $25,000 and he was taken to Cumberland County Jail in Portland.

The estimated value of the cocaine is $15,000 to $20,000, Hagan said.

The car’s driver, Dana Santos, 23, of 9 Cottage St., New Bedford, was issued a summons and charged with possession of a usable amount of marijuana.

According to the arrest report, Santos also had adhesive tape along his groin area — but no drugs, other than the marijuana, for which he was charged — and recent gunshot wounds.

A third passenger, from Fall River, Mass., was not charged.

“It was a great traffic stop,” Hagan said. “Officer Swan did a very good job reading behavioral signs and other observations during the stop, and building on them.”

Lisbon police brought a drug sniffing dog. Sagadahoc County sheriff ’s deputies also aided in the stop.
