Question to the Ministry of Justice:

To ask the Secretary of State for Justice, how many prison visitors have been arrested in each of the last four years; and how many of those arrested have been (a) prosecuted and (b) convicted of an offence.

Records of visitors arrested and of subsequent prosecutions and/or convictions are not held centrally. To provide this information would involve requesting and examining any information held locally at all prison establishments which could only be achieved at disproportionate cost.
