Video shows arrest of Texas woman later found dead in cell

A Texas state trooper tried to pull black motorist Sandra Bland out of her car, then drew his stun gun and threatened her after she refused to follow his orders during a traffic stop.

A police video shows what happened during the encounter, days before Ms Bland was found dead in a jail cell, in a case that has caused her family and supporters to dispute that she hanged herself, as authorities have said.
