6ABC reports that former narcotics officer Jeffrey Walker pleaded guilty to robbery and weapons charges in a case that could lead to a string of more, high-profile police corruption cases in Philadelphia.
Since he was arrested Walker has been cooperating with the FBI. Walker has also been naming others.
His lawyer says the investigation involves too many cops and civilians to count, and he says there’s a lot of money involved.
"At the end of the day it's going to result in a significant amount of indictments, we believe, and significant police corruption being uncovered in the city," (defense attorney Thomas) Fitzpatrick said.
Six other narcotics officers have been removed from active duty, 6ABC reports.
