“Fat Leonard” is on the loose.

The former military contractor at the center of the largest corruption scandal in the history of the US Navy escaped from house arrest in San Diego over the weekend by cutting off his GPS monitor — weeks before he was to be sentenced for defrauding the service of at least $35 million.

Leonard Francis, who had been under home confinement since 2018, was reported missing Sunday by police after the federal Office of Pretrial Services — which had been monitoring him — reported a problem with the GPS monitor.

Police conducting a welfare check found the discarded ankle bracelet at Francis’ home and contacted US Marshals.

The San Diego Regional Fugitive Task Force was activated and Naval Criminal Investigative Services is also involved.

Supervisory Deputy Marshal Omar Castillo said neighbors reported seeing U-Haul trucks coming and going from Francis’ multimillion-dollar home in a gated community, the San Diego Union-Tribune reported.

“He was planning this out, that’s for sure,” Castillo told the newspaper. 

Francis, a Malaysian citizen who tips the scales at 350 pounds, was arrested in 2013 and pleaded guilty in 2015 to bribery and fraud charges.

Prosecutors said Francis offered $500,000 in bribes — as well as travel, luxury goods and prostitutes — to Navy officers in exchange for classified information that gave him a leg up on bidding for military contracts to service ships at ports controlled by his Singapore-based company across Southeast Asia.

In all, Francis and his company overcharged the Navy more than $35 million. 

A total of 33 people have been charged in connection with the scandal, 22 of whom have pleaded guilty — including 17 Navy officials.

Francis faced up to 25 years in prison at his sentencing, which is due to take place on Sept. 22.
