SAN DIEGO -- An investigation was continuing Thursday into the theft of money from the San Diego Hispanic Chamber of Commerce, police said.

"It's moving along and going forward," said Detective James Borg of the San Diego Police Department's Financial Crimes Unit.

The exact amount of money that was taken from the chamber was unclear, Borg said, saying the chamber did not specify how much was stolen.

Borg said no arrests have been made in the case, although there is a single suspect. He would not provide any other details. Despite some broadcast media reports to the contrary, Borg said chamber President and Chief Executive Officer Linda Caballero-Sotelo has never been under investigation in connection with the theft. Caballero-Sotelo said she, in fact, was the one who reported the theft to police.

Caballero-Sotelo remains on the chamber's staff as president and chief executive officer.

Sources close to the chamber told the San Diego Union-Tribune that a former employee was the primary suspect, and the money was stolen through forged checks.

In an e-mail to the paper, the chamber's board chairman, Joseph Casas, said: "We are saddened by the discovery, as a result of the implementation of our improved financial procedures and protocols, that a longtime employee stole money from out chamber. We are prosecuting the individual to the fullest extent under the law."

The Hispanic Chamber of Commerce provides business networking and other assistance to Latino-owned businesses, and has in past years sponsored an annual mariachi music festival at the Del Mar fairgrounds as a fundraiser.
