From the Brockwell Tranquility FB Group: Oh dear, ...it seems lambeth have been telling porkies. I have just received a reply to an FOI request made to the Met Police. At no point did the Met Police refuse to police LCS if a perimeter fence was not used. Also, the Met Police did not insist or even demand that a perimeter fence be used, but did mention that the perimeter could be made more secure as it was found to be "porous". The wall was only mentioned as an option amongst other options to resolve this.
