A Norwalk man is facing multiple drug charges, including three counts of selling crack cocaine, following an investigation by the New Canaan Police Investigative Division, Norwalk Police Special Services Division and the Stamford Police Narcotics and Organized Crime Squad.

On Friday, Norwalk Special Services Division obtained a search warrant for the residence of Mario Ribeiro, 29, of 43 Scribner Ave., following an extensive narcotics investigation after New Canaan police obtained information that Ribeiro was selling crack cocaine throughout the area.

While searching his residence, police discovered more than 7 grams of crack cocaine, individually packaged for sale, according to the report. Police also seized cash and prescription medication not kept in a prescribed container that was bagged for sale, the report stated.

The New Canaan Police Department obtained three arrest warrants for Ribeiro for the sale of crack cocaine to an undercover police officer on three separate occasions. New Canaan police charged Ribeiro with three counts of sale of crack cocaine and three counts of possession of cocaine.

Norwalk police charged him with possession of crack cocaine, possession of crack cocaine within 1,500 feet of a school, illegal possession/sale of a controlled substance, illegal possession/sale of a controlled substance within 1,500 feet of a school.

Ribeiro was arraigned in Norwalk Superior Court Friday morning and is being held in lieu of $150,000 bond.

New Canaan Police Chief Leon Krolikowski said in the coming months, the department will be aggressively targeting those who possess and sell narcotics in town.
