Federal investigators have found no evidence that the disgraced Wall Street titan broke the law.

“After 18 months of investigation, the criminal probe into Jon Corzine is now being dropped,” a person with knowledge of the probe told The Post.

“There is no evidence of criminal wrongdoing,” this person said.

The Justice Department’s decision to drop the case is sure to come as a relief to Corzine, who has been widely blamed for MFG’s bankruptcy — as well as the misuse of some $1.6 billion in customers’ funds.
