CCTV:July 02/09,Miami,Police have issued a safety alert after a 49-year-old resident was robbed of her purse with all of her bank and identity cards and cash and her book bag while putting gasoline in her car. The entire short incident was captured on surveillance tape from the Chevron station at 130th St. and Biscayne Boulevard.

The victim, Dana Ariton, said she was on the way home from her classes at Miami-Dade College when she pulled in to the station to get some gasoline at noon on Thursday, July 2nd. On the surveillance tape, a man in a white car pulls up, walks over to her, studies her and then ducks down as she looks his way while she is getting gas. He then quickly opens her car door and takes her purse and book bag before taking off.

Ariton, who grew up in Romania, told CBS4 News reporter Peter D'Oench that she didn't even know she had been robbed until she got home. "This was very bad and I am shocked," Ariton said. "I've been in this country for 17 years and it has never happened this way. I came home to take my belongings out and I opened the door and I saw nothing there. I closed the door and then opened the door. I couldn't believe it."

Ariton told D'Oench she's upset. "I can't believe that some people are born and grow up and instead of going to school and having an education and doing better things for society, they do this to people."

She said she thought she had locked her doors. "They are automatic and your press the button and they should close," Ariton said. "I didn't realize. I didn't check. And now I check every day."

Although you may not think about locking your car while you are filling up your tank, police say you should take precautions. "In this day and age," said Police Lt. Neal Cuevas, "you should think about locking all your doors and not leaving anything in plain site. Criminals are waiting for opportunities like this."

Several drivers we spoke with say they always lock their doors while getting gas. Irina Yusupoe of Miami Beach said, "When I'm there at the station, I lock the doors when I go to pay and I lock the doors when I get gas."

Jocelyn Taveras, a recent graduate of Barry College and a Rhode Island native, explained, "I was just taught to be careful. My Dad taught me to be cautious."

"Now I'm very cautious," said Ariton. "This will never happen again, never. Thank God they have this on tape. I hope somebody will come after him."

Ariton says her biggest loss was her book bag with all of her work from Miami-Dade College inside it. Ironically, she hopes to some day work in a crime lab so she can help criminals like the one who robbed her. "I also want to help catch all sorts of predators," she said. Ariton hopes to get her B.A. within two years.
