COLLINGSWOOD, N.J. (CBS) –Authorities have arrested and charged a Florida man with kidnapping a 12-year-old girl who police recently found safe in Philadelphia.

Liam Heim, 21, is charged with allegedly taking Kayla Sparano who had been last seen by a friend at Collingswood High School on Wednesday during the day, but she was later found unharmed on Bartram Avenue on Friday night.

Heim faces one count of first-degree kidnapping and one count of third-degree endangering the welfare of a child, according to authorities.
