Cops busted a Clinton Hill crack and marijuana ring and nabbed 11 individuals suspected of selling drugs on the street, from an apartment building at the corner Putnam and Grand Avenue avenues, and out of a barbershop and two t-shirt stores. In an investigation dubbed "Operation Grand Slam," undercover officers infiltrated the ring and made 18 purchases of crack cocaine before executing a warrant on Oct. 29. During a raid, police recovered 75 grams of crack — which carries a street price of about $10,000 — from the barber shop, two guns and nearly two pounds of weed from the t-shirt shops, and a third gun from the home of a t-shirt store manager. The investigation came in response to community complaints.
