Salt Lake police Thursday were looking for what could have been a cross-dressing man who investigators say tried to abduct two young girls from the Salt Lake Main library.

About 4:30 p.m. Wednesday, a person described as a "black female" approached an 8-year-old girl and her 5-year-old sister at the library, 210 E. 400 South.

The suspect grabbed the two girls by their wrists and tried to pull them outside the building, said Salt Lake police detective Jeff Bedard. The 8-year-old was about to scream for help when the group spotted a security guard and the suspect let go of the girls and exited the library, he said.

The girls ran to their mother and she called police.

The suspect was described with a thin build, black hair pulled into a ponytail and bun, and was last seen wearing a blue/green shirt, a "sparkly" skirt with a black belt and high heeled shoes.

A security officer spotted a suspect matching that description by the TRAX station but believed it was a man dressed as a woman.
