Released Under Investigation (745A/22)


1) For each year from the start of 2019 up to now, the number of people who have been released under investigation by West Midlands Police.

2) I would like a breakdown of the crimes these people were suspected of committing.

3) I would like to know how many people remained under investigation for at least a year (only for cases which are at least a year old).

4) Of the total number released under investigation in each of 2019, 2020 and 2021, how many are currently still released under investigation?


We can confirm that relevant information is held by West Midlands Police. However, while the majority of the information is attached to this email, I am not required to release all of the information requested. Please find attached our response.

Please note however, due to a major system change, it has not been possible to extract the information for question 4. We are hopeful that an update will be implemented in the future, but no timeframe has yet been established as to when this might be.


The withheld information is exempt by virtue of the following exemption:

Section 31(1)(a)(b) – Law enforcement

This exemption and explanatory notes are shown here:

In line with the above, I am required to complete a Prejudice Test/Public Interest Test (PIT) on disclosure. Please find this PIT attached (745A_PIT).
