When police stopped Adrian S. Tenecela, 25, of 21 Town Hill Avenue, Danbury, for driving with an excessively loud exhaust pipe and an un-illuminated license plate, they learned his insurance was expired and he had a small amount of suspected marijuana in his car.

Tenecela was northbound on Danbury Road around midnight when a patrol officer heard the noise coming from the exhaust pipe of his 1998 Acura Integra.The officer also noticed Tenecela’s license plate lamps were not lit, police said.

Stopped near Sugar Hollow Road, Tenecela gave police an insurance card that had expired in October 2015.

The investigating officer also smelled marijuana, and K-9 Unit Enzo hit on Tenecela’s Acura.

A subsequent search reaped less than one-half ounce of suspected marijuana from the center console of the car.

Tenecela was issued a misdemeanor summons for insufficient insurance, possession of less than one-half ounce of marijuana, unnecessary noise, and defective license plate lamps.

He was released on a promise to appear at Norwalk Superior Court on April 29.
