The case of a Rastafarian woman left naked in a police cell shows officers need greater understanding of minority groups, ex-senior officers have said.

Yvonne Farrell said she was “humiliated” after sitting naked in a cell for three hours following her arrest by Hertfordshire Police.

She successfully sued for wrongful arrest, receiving an apology and £45,000 in compensation.

Hertfordshire Police said it “didn’t get everything right on this occasion”.
