Upper Darby police said Aishana Clayton, 26, was caught stealing a package of Pampers diapers at a Pathmark store Saturday and was taken to the security office where she struggled with a female security guard, the Philadelphia Daily News reported Wednesday.
The guard grabbed onto Clayton's shirt, but the suspect managed to get free of the garment and fled the store topless.
"Her breasts were swinging as she ran to the car," Police Superintendent Michael Chitwood said.
Clayton fled in an older-model Buick, which was later found abandoned.
Police said they are searching for Clayton, who has four prior convictions for retail theft and arrests for aggravated assault and attempted murder.
