More than 1,000 Metropolitan Police officers are currently suspended or on restricted duties, the force has said, as it tries to root out rogue officers.
The Met's Stuart Cundy said the number of affected officers was almost the size of a small police force, with one in 34 suspended or restricted.
In figures described as 'eye-watering', the Met - Britain's largest force which employs 34,000 officers - also revealed:
Speaking to reporters at New Scotland Yard, Mr Cundy said there were plans to hold around 30 misconduct hearings and 30 gross incompetence hearings each month, meaning that around 60 officers a month could face the sack.
The Met has been shaken by a series of scandals in recent years, and was subject to a blistering review by Baroness Casey earlier this year.
Zoe Billingham, formerly Her Majesty's Inspectorate of Constabulary, warned that the issue was likely to worsen before improving.
