Topeka police are seeking the public’s help in finding a man they say tried to kidnap a 7-year-old girl after a school bus dropped off her and her 11-year-old sister last week.

Authorities say the children were coming home last Tuesday from an after-school program when a man grabbed the 7-year-old by her arm and started pulling her away. The girls told police he said he wanted her to play with dolls with his daughter.

Police say the man ran away after both children began to scream. The 11-year-old girl told authorities that she had seen the man occasionally in the area over the last two months.

Authorities say they’re looking for a white man between 40 and 50 years old with a medium build and some facial hair.
