Two-thirds of the public would not intervene if they saw a group of teenagers drinking and verbally abusing passers-by in the street, a survey suggests.
Only 6% of the 1,784 people in England, Wales and Scotland surveyed by YouGov said they would definitely intervene. A further 21% said they probably would.
Think tank Policy Exchange commissioned the survey and called for "citizen police academies" to be set up.
They could include lessons in making citizens' arrests, it said.
