US police apologise for detaining black family

Police in Colorado have apologised for pulling guns on a black woman and four children they mistakenly arrested.

Video of Aurora officers detaining Brittney Gilliam, along with her six-year-old daughter, nieces aged 14 and 17, and sister, 12, has drawn outrage.

It comes amid a national debate over police tactics and systemic racism.

The police department said the officers mistakenly believed Ms Gilliam's car had been stolen and had been trained to perform a "high-risk stop".

The department has launched an investigation and will cover the cost of therapy for the children.
