Complaints about suspected drug trafficking at an Evanston house led police Friday night to make six drug arrests there, plus the recovery of three guns, crack cocaine and $5,300 in cash.

District 2's Violent Crime Squad, with the Cincinnati Police Department's SWAT team, found about 15 people in the house on Harvard Avenue. They think one of the men they arrested, Anthony Reynolds, 22, was dealing crack cocaine there with his friends in his grandmother's house, said Sgt. Brian Ibold, supervisor of the squad.

Mr. Reynolds and four others were charged with felony drug possession, drug trafficking, or both. Another man was charged with possession of a crack pipe, and another was arrested on an outstanding warrant.

Officers Aaron Jones and Steve Lawson said they found more than 50 grams of crack cocaine in a locked room to which Mr. Reynolds held the key. Depending on how much is sold, crack can go for about $100 a gram, Sgt. Ibold said. The federal Weed and Seed program, a grant the city has for Evanston, pays overtime for officers to work in the neighborhood.
