North Dakota oil boomtown: 'I use pepper spray'

The oil boom has been a blessing and a curse to the North Dakota city of Williston - crime is surging and homeless jobseekers sleep rough in sub-zero temperatures.

The ratio of men to women is estimated to be 10:1 and some women say they are afraid to walk the streets alone.

The BBC spoke to two workers, 16-year-old Hannah Kitzan and Bailey Moreland, 25, at a Williston coffee shop.
