First, I join the noble Lord, Lord Coaker, in expressing my disgust at what has happened to a child—and at school, no less. He is absolutely right to ask the questions he has asked.
I understand that the review by the IOPC, which I assume he is referring to, will be done at pace. His question on the collection of data is also absolutely the right question to ask. What are we doing now? I understand that from December this year, we will be including more detailed custody data in the annual police powers and procedure statistical bulletin. It will include the number of persons, including children, detained in police custody, broken down by age, gender, ethnicity and offence type. It will include the number of children detained in custody overnight, whether pre-charge or post-charge, broken down by age, gender, ethnicity and offence type. In fact, the noble Lord will recall that some time ago we banned the detention of children in custody, so I hope that figure comes out as nought.
Crucially, on the question of whether an appropriate adult was called out for a detained child, the review has yet to report but on the face of it, that does not appear to have been the case here. In the case of a detained adult who was declared vulnerable, and regarding the question whether an appropriate was adult called out, there is the time taken for an appropriate adult to arrive and the number of strip-searches carried out, broken down by age, gender, ethnicity and offence type. I am sure that all noble Lords and the other place will be very interested to hear those statistics, and I hope that is helpful at this stage to the noble Lord.
