A POLICE officer was stripped naked below the waist before male colleagues kicked, stomped and stood on her, shocking footage played to an anti-corruption hearing shows.

The public Independent Broad-based Anti-corruption Commission (IBAC) hearings, which started in Ballarat this morning, are examining a series of complaints against 158 Victoria Police officers based in the city.

It is twice the number lodged against officers in Frankston, a similar-sized station.

Counsel assisting Jack Rush QC said the hearings would examine four incidences in which police are accused of using excessive force.

The Herald Sun reported today one of the alleged victims was a serving police officer who was humiliated by other officers, pepper sprayed before being placed in a hot shower - which exacerbates the effect of the spray.

The officer was on leave on January 14, 2015 for personal issues, and was arrested for being drunk and disorderly.

Footage played to the hearing showed the 51-year-old woman known as “Person A” being stripped while handcuffed, left naked from the waste down while male officers stood on her legs.

“She was kicked, stomped, a stood on,” Mr Rush said.

The woman was later left in a cold cell with no pants or blanket before she was released after 16 hours.

The hearing continues.
