Question to the Home Office:

To ask Her Majesty's Government what percentage of police investigations in England and Wales have been (1) closed, and (2) written off, within 24 hours of the crime being reported to the police, for the most recent year for which figures are available.

The Home Office publishes information on crime outcomes, including the proportion of crimes that are assigned each outcome and how long it took for these outcomes to be assigned.

Information on the proportion of outcomes assigned by outcome type can be found in Table 2.2 in the data tables published alongside Crime Outcomes in England and Wales, year ending March 2017, available here: https://www.gov.uk/government/statistics/crime-outcomes-in-england-and-wales-2016-to-2017

Information on how long it has taken for these outcomes to be assigned can be found in Table 5.2 in the same link. This table includes information in the proportion of outcomes that were assigned on the same day as the offence was recorded.

We expect the police to investigate all crimes, and investigations can be reopened at any point should new evidence come to light.
