A man with an expired real estate license is accused of keeping a renter's security deposit instead of turning it into the property manager.

Miami-Dade police said the agent, Adolfo David Vega, 31, of Miami Lakes, listed a property for rent on Craigslist and showed it to a woman.

The woman gave him $1,150 for the first month, $1,150 for the last month and another $1,150 for a security deposit, according to the arrest affidavit.

Miami-Dade police said Vega gave the brokerage company $1,150 and kept the other $2,300.

When the woman moved in, the listing agent told her that she had only received the first month's rent, not the last month's rent or the security deposit, police said. The agent and the woman tried to contact Vega, but when they couldn't, they called police.

Vega was arrested. According to the arrest affidavit, he admitted that he had failed to turn in the $2,300.

"The defendant admitted that keeping the money was a mistake and he stated that he was embarrassed for having done that," police wrote in the arrest affidavit.

Vega faces a grand theft charge.

Miami-Dade police said detectives believe there may be other victims. Anyone with information is asked to call Detective M. Fluty of the Northwest District at 305-698-1500.
