Police have arrested a man over the attempted kidnapping of a 10-year-old girl in the city of Philadelphia, which was captured in CCTV footage.

The clip shows the man trying to grab the girl as she walks home with her two-year-old brother in broad daylight, before the boy's screams apparently caused him to flee empty handed.

US media report that the suspect gave himself up after police put out a $10,000 (£6,300) reward for his capture.
