Sex crimes: Police disciplined for abuse cases
More than 500 police have been disciplined in the past five years for sexual misconduct or have quit while under investigation.
Dozens of the officers were jailed for depraved offences including child abuse and rape.
In 252 cases, police were convicted of sex crimes or sacked.
Det Supt Jackie Alexander, of Notts police, said: "It is really important that forces have an open mind that abuse can occur because if we can't protect the vulnerable, who can?"
She added that her force had been "proactive" in tackling the problem in recent years.
Our probe comes in the wake of constabularies being accused of failing to properly investigate rich and powerful paedophiles including TV star Jimmy Savile.
Monster: Jimmy Savile
We asked every force for details of their inquiries into claims of sexual misconduct against their officers between 2010 and now.
More than 1,500 police were investigated in total.
Shocking cases included former Warwickshire police officer Robert Tedds who pleaded guilty last year to making indecent images of children and taking photos up strangers' skirts.
