HC Deb 22 December 1983 vol 51 c335W
Mr. Dubs

asked the Secretary of State for the Home Department on how many occasions in each of the last four years persons held in custody by the Metropolitan police have been discovered to have hidden in body orifices, razor blades or similar articles which could be used to cause physical injury to themselves or to others.

Mr. Hurd

The information requested is not collected centrally, but we know that there have been such cases, that of Mr. David Martin being the most recent.
