SAN DIEGO - A second elderly woman has come forward with a report that a pair of scam artists convinced her to withdraw a large sum of money to pay for bogus car repairs, San Diego police said today.

The second incident, in University City, is similar to a theft from an elderly lady in La Jolla on Friday.

In the latest incident, an 87-year-old woman was driving home from Vons on Governor Drive Friday when two men in a green van pulled up next to her at a stop light trying to get her attention, police said.

She rolled down her window, and they told her the tire was about to fall off the car. They said they were mechanics and could fix it for $7,500, according to an officer.

One of the men offered to take her to the nearest bank. She got into the van while the other suspect stayed with the car at a fast food restaurant's parking lot on Governor Drive near Genesee Avenue.

The woman withdrew some cash - police did not say how much - and gave it to the suspect, who returned her to her car. The other man told her the car was fixed and she could leave.

In a case reported yesterday, an 89-year-old woman was coerced into withdrawing $4,000 by a would-be mechanic who offered to repair her 1966 Mustang, according to police.

She was approached in a Vons parking lot on Girard Avenue and told that the vintage Mustang needed repairs costing $4,000 to $7,000.

He told her to withdraw money from a Wells Fargo Branch inside the Vons, but the manager, who knew the woman, was suspicious and refused to turn over the money. The manager saw her get into an old black station wagon with the suspect.

She was taken to another branch and withdrew $4,000. The man took the cash and left her at a McDonald's where she called a taxi cab and returned to the La Jolla Vons.

In both cases, the suspects are described as Hispanic males in their mid to late 20s.
