There hasn't been an incident since November 25, but police are still asking women in the area to be extra careful.

The man was wearing a mask, but Lake Forest police have released A sketch of a man someone had seen in the area the same day who matches the description of the person they're looking for.
Five days later, in Highland Park, a similar incident happened at a strip mall on Elm Place. A man confronted a woman as she was getting into her car. He threatened to use his stun gun on her and demanded her rings. After she gave them to him, he ran off.
"It's shocking, alarming. I live right down the street and I do my shopping around here, Walgreens, Sunset. Just to hear there are robberies all of a sudden, it's terrible," said Jessica Goldsmith.
