Aventura police are investigating allegations that a former manager of an Aventura luxury condo embezzled more than $500,000 from the condominium association.

The alleged incident took place at The Atlantic II, 21150 Point Pl., according to a report filed with the Aventura Police Department. The Atlantic II is one of three high-rise condos at The Point, an Aventura gated community.

The former manager, Lourdes Rodriguez, has not been charged.

Aventura Police Det. Emilio Perez said last week the case is open and the department is working with the Miami-Dade State Attorney’s Office, which would neither confirm nor deny its involvement.

The case began in February 2010 when the condominium association’s auditor alerted the condo board of “suspicious activity on the business account,’’ the report said.

Gary Green, the condo board president, said the board hired Edward Sachs of Appelrouth Farah & Co., an accounting firm in Coral Gables, to look into the account’s history from Jan. 1, 2007 to Feb. 1, 2010.

The accountant’s report detailed that “$546,521.57 was stolen from the account,’’ according to the police report. The association hired an attorney, Perry Adair of the Fort Lauderdale law firm of Becker & Poliakoff, to handle the matter. In early February, Adair and the condo board members confronted Rodriguez.

She confessed and resigned, Green said.

“She said she was very sorry, very embarrassed and wanted to make it up to us,” Green said.

Two weeks later, on Feb. 22, Rodriguez e-mailed residents, apologizing and blaming her actions on a gambling addiction.

“what has made me lose everything I love, my job, my friends, my home, has been an addiction to gambling,’’ she wrote in the e-mail.

“I don’t have words to express the shame, humiliation, and hurt that I feel,” Rodriguez added. “I have no words to express this and I take full responsibility for my actions.”

At the meeting, Rodriguez told board members she wanted to pay back the association but she acknowledged she lacks the funds to do so, Green said. In the e-mail, she vowed to repay the association “no matter how long it may take.”

Green said he had worked with Rodriguez for more four years. She had been the condominium manager since May 2004, he said.

“This was somebody with whom I had been working with very closely for years,” Green said. “She seemed to be honest. I was fooled.”

The association has recouped about $250,000 from its insurance company; a claim for $250,000 is pending with another insurance company. It is working with the Florida Department of Business & Professional Regulation, which issues licenses to condo managers.

A spokesperson for the Tallahassee agency said Thursday the department is investigating a Lourdes Maria Rodriguez-Hernandez who has a Pembroke Pines address. She did not confirm whether that is the same person as in the Aventura case.

Meanwhile, the board has hired a management company, AKAM On-Site, to handle the association’s accounts.

“With a management company we have more sets of eyes dealing with flow of money,” Green said.
