'Fat Rat,' A Most Wanted Chicago Drug Trafficker, Arrested In Alabama

After spending some eight months on the lam after being charged in a federal district court with conspiracy to distribute heroin and other drug charges last November, 40-year-old Chicago Corey Griffin was arrested Thursday in Brent, Ala.

The arrest comes after a nationwide manhunt led by the Federal Bureau of Investigation, according to Reuters. Griffin, a Chicago man who allegedly transported drugs on behalf of a street gang under the alias "Fat Rat," will now return to the Windy City for prosecution.

The hunt for Griffin was part of "Operation Blue Knight," a coordinated effort between hundreds of Chicago police and federal agents to locate some 100 "most wanted" men affiliated with a drug ring and attempt to arrest them on the same day, according to FOX Chicago. In addition to the drug charges, Griffin was previously convicted of battery, aggravated assault and murder and was considered to be armed and dangerous.

Earlier this year, the FBI issued a press release calling for the public's help in finding Griffin, offering a reward of up to $10,000 to anyone providing information that would lead to the his arrest.
