WELLS — A Wells man was arrested in Kittery on Thursday night and charged with aggravated trafficking in heroin. The arrest came as part of a month-long investigation into the drug trade in greater Kittery, and additional arrests are expected, according to state police spokesperson Steve McCausland.

Cole Dalton, 29, was pulled over on Route 236 and a search of his car yielded 18 grams of what is suspected to be heroin, worth $3,000.

After he was taken into custody, agents from the Maine Drug Enforce-ment Agency, assisted by the Wells Police Department conducted a search of his apartment, where further evidence of drug trafficking was discovered, including another quantity of heroin, packaging materials and digital scales, McCausland wrote in a press release.

Investigators suspect that Dalton traveled down to Massachusetts to buy heroin for distribution, and returned to his apartment in Wells where he processed the drug for individual sale to users in the Kittery area. Dalton was brought to York County Jail, and bail was set at $30,000.

The investigation into drug trafficking in Kittery is an ongoing collaboration between the MDEA York District Task Force and Kittery police.

Police urge those with information about this incident or any illegal sale of drugs to contact Kittery police at 439-1638, any MDEA office or the MDEA tip-line at 800-452-6457.
