Police have released video footage of the rescue of a woman who was held prisoner in a storage unit by a serial killer for two months.

Officers found Kala Brown, 30, chained to the wall of the container in South Carolina in November 2016.

The footage shows a group of officers using a saw and crowbar to break into the container where Ms Brown was found chained to the wall with a collar around her neck.

She is sat on the floor with her hands on her head as the police enter.
