According to reports in Mexico, former four division world champion Juan Manuel Marquez (56-7-1, 40 KOs) is looking to get another knockout, but this time it's not against a fighter - but against one of the largest banks in the world.

The Mexican veteran has filed a lawsuit against JPMorgan Chase & Co., alleging that bank officials conspired with his former tax preparers to steal $ 2.3 million.

Marquez's lawsuit, filed in Los Angeles Superior Court last Friday, is looking to get triple the amount in damages.

The text of the complaint states that "the plaintiff believes that Chase agents, officers and/or employees were active participants and co-conspirators in criminal transactions."

He also says the bank failed to adequately train their employees.

Marquez's complaint alleges that his tax preparers were a father-son duo who opened accounts at the Chase branch on Philadelphia Street in the Los Angeles area of Whittier.

According to the lawsuit, tax preparers, with the help of a notary, falsified Marquez's name on documents to open accounts at Chase in March 2013, using money that didn't belong to Marquez and without his knowledge. Then, they allegedly deposited Marquez's tax refund checks with sums ranging from $400,000 to 1.4 million.

Marquez says the IRS sent him a letter, through his new accountant, in April 2015 - and the letter included copies of the allegedly stolen refund checks.

Marquez, 43 years old, has not fought since 2014, but has not officially retired from boxing. He last saw action in May of 2014, when he won a twelve round decision over former world champion Mike Alvarado.

The Mexican fighter is scheduled to meet with Zanfer Promotions in the coming days to finalize the details of his next fight. Marquez wants to return on a date in June. He won't mention any of the opponents until a deal is reached with Zanfer for the date, location and venue.
