Speaking to BBC Radio WM, Philip Ingram said it was "important that we question our public officials" but that it was an "operational police matter" and officers would be doing "everything they can to keep the public safe".

"They have to make sure they're carrying out their investigation in a way that allows them to gather their evidence that whenever they arrest someone they can get a successful prosecution.

"And therefore it's a balance between what you tell the public and how much you have got going around within the police so that they can do their job.

"Often if you release too much information that can then lead to the police lines being swamped... and put the public at greater risk."
