Ten inmates who broke out of a New Orleans jail Friday had prepared for their escape, and possibly had help, officials said.

At least a dozen law enforcement agencies entered the third day of a manhunt on Sunday for seven of the 10 men who escaped from a New Orleans jail by fleeing through a hole behind a toilet. A spokesperson for the Louisiana State Police confirmed in an emailed statement that the seven men remained at large Sunday.

Officials are offering $12,000 for information leading to an arrest after 10 inmates escaped a New Orleans jail. Three have been recaptured so far.
