Wiltshire Police has launched an investigation into reports of voyeurism at a shopping centre.
The offence – of secretly recording a person doing a private act – is said to have taken place at The Brunel in Swindon at about 2pm on 28 September.
The force has released a CCTV image of two potential witnesses they would like to speak to, and need the public’s help in identifying them.
A spokesperson said: “We believe these two may be vital witnesses in our enquiries. If this is you, or you recognise the pair please contact us on 101 quoting reference number 54230106780.”
