In what police are calling a significant bust, two out-of-state men were arrested Monday on multiple drug-related charges while sightseeing in Westport.

The suspects were reportedly driving through town on their way from Massachusetts to Florida when they were pulled over at approximately 11:30 a.m. for a series of traffic violations -- failure to stop at a red light at the intersection of Riverside Avenue and Post Road, and performing an illegal U-turn on Wilton Road, according to police.

The arresting officer reportedly developed reasonable suspicion during the stop and obtained consent to search the vehicle, a bronze Chevrolet Impala. As the passenger exited the vehicle a plastic bag containing what was determined to be Oxycodone pills fell from his waistband, police said.

"We're very good at discovering deception," said Westport Police Lt. Arthur Belile.

In all, police uncovered 309 pills of various dosages, 1.7 grams of marijuana, a box of plastic bags, a scale, assorted drug paraphernalia and $789.95 in small bills.

Belile said the "street value" of Oxycodone is generally $1 per milligram. Of the 309 pills, he said 187 were 30 milligrams, 37.5 were 15 milligrams, 81 were different levels and three were of an undetermined strength, putting the estimated value in excess of $6,000.

"This is a very significant bust," Belile said.

Arrested on charges of sale/distribution of narcotics, possession of a controlled substance, illegal possession of marijuana and possession of drug paraphernalia was Ryan O'Donnell, 19, of Port Orange, Fla.

O'Donnell, the driver, is being held in lieu of a $50,000 bond and is scheduled to appear in Norwalk Superior Court on Sept. 9

Also arrested on the same charges was the passenger, Robert O'Neill, 32, of Rockland, Mass. He was being held in lieu of a $10,000 bond and is scheduled to appear in Norwalk Superior Court on Sept. 9.
