There are 15,576 CCTV cameras in London Underground train stations How long are recorded CCTV footage kept before being destroyed on London Underground train stations’ cameras? Data is usually held for around 14 days before being overwritten. Information on how to access footage of yourself from these cameras is published at https://tfl.gov.uk/corporate/privacy-and-cookies/access-your-data#on-this-page-4 Once CCTV footage has been destroyed, can it be re-accessed or retrieved in instances involving the police or by the courts? Once the data has been deleted, it cannot be recovered The number of sexual assault/harassment cases reported at each London Underground train station in 2019 and 2020. Please see the attached spreadsheet, showing the numbers of recorded crimes for sexual offences. The drop in recorded crimes from 2019 to 2020 is largely as a result of the pandemic (i.e. reduced passengers using public transport and reduced opportunities for offending). Please note that these figures have been provided by the BTP and are not taken from live crime data. Numbers may have been updated since received by TfL, so for the most up-to-date numbers, you may wish to make a request to the BTP. If this is not the information you are looking for, or if you are unable to access it for some reason, please do not hesitate to contact me. If you are considering submitting a further FOI request please think carefully about whether the request is essential at this current time, as answering FOI requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. Where requests are made, please note that our response time may be impacted by the current situation.
