Request
I am requesting the States of Jersey Police criminal investigation statistics for the past five years:
A
Total number of criminal investigations undertaken.
B
Total number of criminal investigation lasting more than:
one year
two years
three years
C
If any investigations have lasted more than three years, please explain the reasons for the length of time taken.
D
The average duration of a criminal investigation.
Response
A to D
In instances where there are multiple crimes involving the same perpetrator, same victim, and at the same time, only the most serious is counted for statistical purposes.
For example, if an individual commits an assault, and then damages the victim’s phone, only the assault would be a recorded, counted crime. This is in compliance with Home Office counting rules.
Year | Recorded, counted crime | Length of investigation | Average length of investigation (days) |
1 Year | 2 Years | 3 Years | More than 3 years |
| 2016 | 2,904 | 26 | 3 | 1 | 1 | 38 |

| 2019 | 3,394 | 18 | - | - | - | 32 |
| 2020 | 2,972 | 8 | - | - | - | 35 |

The one investigation in 2016 that took longer than three years to conclude was a complex international money laundering case under the Proceeds of Crime (Jersey) Law 1999.
